Question

Answer the questions about the characteristics of the elements in group 1 (the alkali metals). What happens when the elements in group 1 react with bromine? No reaction a salt is formed with the general formula MBr2 a salt is formed with the general formula MBr What happens when the elements in group 1 react with water? Hydrogen gas is released no reaction What happens when the elements in group 1 react with oxygen? No reaction an oxide is formed with the general formula MO an oxide is formed with the general formula M2O Which group 1 element reacts the most vigorously? Na Rb Li K Cs Which group 1 element exhibits slightly different chemistry from the others? Li Na Cs K Rb

See explanationExplanation:The elements in group form univalent positive ions and element in group 17 form univalent negative ions. Hence, when a group 1 element reacts with a group 17 element, a compound of the sort MX is formed. Hence, when a group 1 element reacts with bromine, a salt is formed with the general formula MBr.Elements of group 1 are highly electro positive metals. They react with water to form the metal hydroxide and release hydrogen gas. Hence, when group 1 elements react with water, hydrogen gas is released. A group 1 element forms a univalent positive ion while a group 16 element forms a divalent negative ion. Hence, when a groups 1 element reacts with oxygen, the compound formed must have the general formula M2O.The reactivity of group 1 metal increases down the group hence Cs is the most reactive group 1 element.Lithium displays a slightly different chemistry from other group 1 elements because of its small size.
