Question

Give reason the oxidising power of an element increases from left to right along the period in the period table

Answer 1

The element oxides to complete there octet shell from the left to right of the periodic table.

Answer 2

The electropositivity (the power to give away electrons) increases as we move right to left in the periodic table.This results in a higher valence since electropositivity affects the valence or here,the oxidation number.
Hence the oxidation number/oxidizing power increases as we move from left to right in the modern periodic table.
