- Metals and Non-Metals
In the periodic table, elements are classified into metals and non-metals.
Groups I – III are metals, they donate their valence electrons.
Groups IV – VIII are non-metals that accept or share electrons.
Group 0 are the noble gases, their outer electrons are filled up.
Semi-metals or metalloids occur along the boundary line. For example, carbon is a non-metal, silicon and germanium are metalloids, while tin and lead are metals.
