Question

How to know which is the most electronegative and electropositive element if the group and period details is given

Answer 1

The alkali metals are the most electropositive. Cesium is the most electropositive of the stable elements.Francium, while unstable, is theoretically the most electropositive element. Electropositivity increases down groups and decreases along periods (from left to right) on the periodic table.

Answer 2

On the most basic level, electronegativity is determined by factors like the nuclear charge (the more protons an atom has, the more "pull" it will have on electrons) and the number/location of other electrons present in the atomic shells
