Key learning points. Group 1 elements are very reactive and their reactivity increases down the group. Moving down Group 1 elements, atomic mass, density and melting points increase. In chemical reactions, atoms of Group 1 elements lose one outer electron leaving full electron shells.
Group 1 and Group 2 oxides and hydroxides react with dilute acid to form a salt and water. This is a type of neutralisation reaction. The salt formed depends on the acid used: Hydrochloric acid forms chloride salts. Sulfuric acid forms sulfate salts. Nitric acid forms nitrate salts. Example: Group 1 oxide Example: Group 2 oxide Example: Group 1 ...
Group 1 elements. The Group 1 metals are known as the alkali metals. They form alkaline solutions when they react with water. The Group 1 metals are lithium, sodium, potassium, rubidium, caesium and francium and they are found in the first column of the periodic table. The alkali metals share similar characteristic chemical properties because ...

Group 1 metals are all soft metals with lower densities than other metals, and become more reactive down the group. Group 1 metals react with water to form an alkaline solution and hydrogen, which is why they are called alkali metals. Group 2 metals react with dilute acids to make a salt plus hydrogen gas.
