Question

why does election positivity of elements increase down a group​

Answer 1

Answer:

down the group electropositivity increases.

Explanation:

because down the group inner shell electron increases. down the group screening effect increases. effective nuclear charge decreases down the group . so size increases .easy to remove the electron .therefore electropositivity increases.

Answer 2

Explanation:

Electropositivity is the measure of an element's ability to donate electrons. It is the opposite of electronegativity. As the size of atom increases,its nuclear charge decreases and its tendency to donate electrons increases and therefore electropositivity increases down the group while it decreases across a period.
