Question

define electron infinity and explain why it decreases along a period and increase down the group?​

Answer 1

Answer:

The less valence electrons an atom has, the least likely it will gain electrons. Electron affinity decreases down the groups and from right to left across the periods on the periodic table because the electrons are placed in a higher energy level far from the nucleus, thus a decrease from its pull.
