Groups on the periodic table • Vertical groups on the periodic table share similar properties: • 1. They all have the s_____ number of e_____ in their o______ s_____. • 2. They share similar r_______ properties. • 3. Metals become more r______ as they move down a g_____ and non-metals become less reactive as they move down the group. • 4. Groups are m_____ r________ on the outside of the table.
Important groups- colour these groups on the periodic table (each a different colour). • Alkali metals- (group 1). • Alkali earth metals- (group 2). • Transition metals- (group 3-11). • Halogens- (group 17). • Nobel gases/inert gases- (group 18).
Copy these notes under the table you have coloured in. • Alkali metals-(group 1). Highly reactive and never found in element form in nature. • Alkali earth metals- (group 2). High melting point, found in element form in nature. • Halogens- (group 7). Highly reactive and only found in the environment as compounds. • Nobel gases/inert gases- (group 8). Unreactive because they have a full outer shell.
