Mg burns with a bright white flame. It explains why it is difficult to observe many tidy patterns. Chemistry. Part of. Ba + H2O ---> Ba(OH)2 + H2. Because they are not as active as the alkali metals, most of these elements form oxides. The Oxygen is -2 in the OH-ion, and -2 in water. This is an A2 Chemistry PowerPoint Presentation on period 3 elements – reactions with oxygen. Group 2 reactions Reactivity of group 2 metals increases down the group Mg will also react slowly with oxygen without a flame. The Hydrogen is +1 in the OH-ion and HCl, and +1 in water. ... State and explain the trend in melting points of the elements down Group II from Mg to Ba. metal oxides + water You will find this discussed on the page about electronegativity. This is compared to non-metals when the reactivity decreases working down a non-metal group such as group 7. M (s)----> M 2+ (aq) + 2e- The products of these reactions are what we might expect. There is a diagonal relationship between lithium and magnesium. All Group II elements react with acid to give hydrogen gas and the corresponding salt; M(s) + H⁺(aq) → M²⁺(aq or s) + H2(g) ; where M = A Group II element. These compounds are usually ionic in nature. e.g. **By the end of this lesson students should be able to: **1. 2Mg + O2 2MgO This needs to be cleaned off by emery paper before doing reactions with Mg ribbon. Group 2: Group 2 elements are known as alkaline earth metals. The group 2 metals will burn in oxygen. 1.3.2 (a) Redox Reactions of Group 2 Metals. Ca + 1/2O 2 → CaO Mg + 1/2O 2 → MgO.

Ca + Cl 2 → CaCl 2. B. Chemical properties. Lesson 2: Group 2 Compounds. In these reactions, the elements that react with oxygen are all metals . 3.1.2 (d, e) Reaction of Group 2 Oxides with Water and Group 2 compounds as Bases. with acid to produce hydrogen gas and the corresponding halide salt. When these metals (M) are heated in oxygen they burn vigorously to produce a white ionic oxide, M2+O2-. Reactions with dilute hydrochloric acid All the metals react with dilute hydrochloric acid to give bubbles of hydrogen and a colourless solution of the metal chloride. 8. Their oxides and hydroxides are alkaline in nature. 1. Learner Activities10 The elements of Group 2 are beryllium, magnesium, calcium, strontium, barium, and radioactive radium. These elements are divided into two categories i.e, alkali metals or group 1 elements and alkaline earth metals or group 2 elements. Exposed to air, it will absorb water vapour from the air, forming a solution. The reaction with oxygen. Again, if you have been working through this section of the syllabus in order, you will already have read the first bit of the page Reactions of the Group 2 elements with oxygen. Reaction with oxygen. It also deals very briefly with the reactions of the elements with chlorine. Examples: M 2 O 3, MO 2, ThO 2. When zinc metal reacts with oxygen gas, {eq}2Zn(s) + O_2(g) \to 2ZnO(g) {/eq}, large amounts of light and heat are released. This is important as elements in the same group will react similarly. 3. know the reactions of the elements Mg to Ba in Group 2 with oxygen, chlorine and water; OCR Chemistry A. Module 3: Periodic table and energy. M = Mg, Ca, Sr,Ba --> I will be using 'M' as the general symbol for a Group II element in this topic. In these two lessons we show how Group II metals burn in oxygen and how the metal oxides formed react with water. Which chemical reactions are likely to have an element as one of its products? 2Mg + O 2MgO Mg will also react with warm water, giving a different magnesium hydroxide product. It also deals very briefly with the reactions of the elements with chlorine. Systems and interactions. The rest of Group II metals react with increasing vigorous going down the Group A redox reaction occurs where an ionic oxide is produced with the formula MO (where M is the group 2 metal) eg– 2Ca(s) + O2(g) ----> 2CaO(s) 2Sr (s) + O2 (g) ----> 2SrO (s) solubility of group 2 hydroxides increase down the group. 2.11.3 investigate and describe the reactions of the elements with oxygen, water and dilute acids; Republic of Ireland. All Group 2 elements tarnish in air to form a coating of the metal oxide. Science. The Chemistry of Group 2. All group 2 elements will react with oxygen to produce a metal oxide-Mg would need to be heated but Barium will react at room temp. Reaction with halogens. eg. This page mainly looks at the reactions of the Group 1 elements (lithium, sodium, potassium, rubidium and caesium) with oxygen - including the simple reactions of the various kinds of oxides formed. Teacher instructions4. Since the alkali metals are the most electropositive (the least electronegative) of elements, they react with a great variety of nonmetals. To onstruct half equations of redox reactions of group 2 elements with oxygen, water and dilute acids and to identify what species have been oxidised and reduced using oxidation numbers. Oxides of all Period 3 elements except Cl and Ar could be made on the same method: burning the element in the air in a combustion reaction when the element will react with the oxygen in the air to produce the oxide of the element. Lithium's reactions are often rather like those of the Group 2 metals. 2.11 Group II elements and their compounds. Anhydrous calcium chloride is a hygroscopic substance that is used as a desiccant. Topic 4A: The elements of Groups 1 and 2. Iodine, I 2 is not reactive towards with oxygen, O 2, or nitrogen, N 2.However, iodine does react with ozone, O 3, the second allotrope of oxygen, to form the unstable yellow I 4 O 9, the nature of which is perhaps I(IO 3) 3.. 8 The Alkaline Earth Metals (Group 2) The alkaline earth metals react (quite violently!) Test yourself questions - Answers8. Chemical world. Ba(s) + O 2 (g) BaO 2 (s) The more active members of Group IIA (Ca, Sr, and Ba) react with water at room temperature. The group 2 consists of the elements beryllium(Be), magnesium(mg), calcium(Ca), strontium(Sr), barium(Ba) and radium(Ra). 2M(s) + O During the formation of these compounds, a large amount of energy is released. Barium, a group 2 element, forms an ionic compound with sulfur, ... An acid contains the elements hydrogen, oxygen, and chlorine and has a molecular weight of 52.46 g/mol. Na 2 O + H 2 O → 2NaOH. Alkaline earth metals also react with oxygen, though not as rapidly as Group 1 metals; these reactions also require heating. The Facts The reactions with oxygen Formation of simple oxides Group 1, 2 and lanthanides form basic compounds of oxygen when they react with dioxygen. reacts with water. Activity 3 – The reactions of Group 2 elements - Answers6. The Group 1 elements, also known as the alkali metals, all react vigorously with water to produce an alkaline solution. It explains why it is difficult to observe many tidy patterns. 3.1 The periodic table. Magnesium is group 2, iron is group 8 and copper is group 11. Junior Cycle.

Reaction of iodine with air. In this video I take a look at some of the different ways in which group 2 elements can react. As I said earlier, they are powerful reducing agents. The general electronic configuration of these elements is ns 1 and ns 2 respectively. To know the reaction between group 2 metal oxides and water **2. As group 2 in the periodic table comprises of metals, the reactivity of group 2 elements towards chlorine increases when working our way down the group 2 metals. Reaction of iodine with water. Beryllium reacts slowly with acids and has no reaction at room temperature. Compare this with the coloured compounds of most transition metals. Redox reactions of Group 2 metals (a) describe the redox reactions of the Group 2 elements Mg - Ba: (i) with oxygen, Group 2 elements react vigorously with oxygen. A reducing agent is the compound that gets oxidised in the reaction and, therefore, loses electrons. Reactions of alkali metals with oxygen. Reaction with acids. They have a low enthalpy of ionization and high electropositive character, the alkaline earth metals have a strong tendency to lose valence electrons. Mg + 2 H2O Mg(OH) 2 + H2 This is a much slower reaction than the reaction with steam and there is no flame. They react violently in pure oxygen producing a white ionic oxide. x This means that what ever they react with must gain electrons. This page mainly looks at the reactions of the Group 1 elements (lithium, sodium, potassium, rubidium and caesium) with oxygen - including the simple reactions of the various kinds of oxides formed. REACTIONS OF THE GROUP 2 ELEMENTS WITH AIR OR OXYGEN This page looks at the reactions of the Group 2 elements - beryllium, magnesium, calcium, strontium and barium - with air or oxygen.

What volume of hydrogen gas is produced if 2.50 g of magnesium metal is dissolved in excess hydrochloric acid in a fumehood with a temperature of 25 °C and a pressure of 1 bar (100 kPa)? Investigate reactions between acids and bases; use indicators and the pH scale; Leaving Certificate. Mg ribbon will often have a thin layer of magnesium oxide on it formed by reaction with oxygen. (3) Both group 1 and group 2 elements produce white ionic compounds. Reactivity of Group 2 elements: x Group 2 metals are reactive: M Æ M 2+ + 2e-x These elements give away 2 electrons when they react. These compounds readily react with water except a few exceptions. 2 Mg(s) + O 2 (g) 2 MgO(s) Calcium, strontium, and barium can also form peroxides. The Group II elements are powerful reducing agents. You may remember that it is difficult to pick out any trends in reactivity in the elements, but there are trends that you can pick out. This property is known as deliquescence. Mg + H2O ---> Mg(OH)2 + H2. Group 2 elements generally react to form compounds in which the group 2 element has an oxidation state of +2, beryllium will also do this but it has a tendency to form covalent rather than ionic compounds.
