The elements which are most abundant by mass in the earth’s crust oceans and atmosphere needs to be determined. Also, the four most abundant elements by mass in the human body needs to be determined. 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. The vertical columns of the periodic table are called as groups and the horizontal rows are called as periods. The complete table contains 18 groups and 7 period.
