The valence electron configuration for the group 3Aa elements needs to be determined. Also, variation of metallic character down in the group and difference between boron and aluminum needs to be explained. Concept Introduction: In the long form of periodic table, the non-metals are mainly placed at the right side of the periodic table that is called as p-block elements. Metals make the 75 % part of the periodic table. Metals are electropositive elements and mainly form ionic compound whereas non-metals are electronegative elements and can form either covalent or ionic compounds.
