Question

When electron affinity and Ionisation potential decreases or increases?​

Answer 1

Answer:

Electron affinity increases accross a period and it decreases down a group.

Ionisation potential increases across a period and it decreases down a group.

Answer 2

Answer:

ANSWER:

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.

Explanation:

If a charge is moving in the direction that it would normally move, its electric potential energy is decreasing. If a charge is moved in a direction opposite to that of it would normally move, its electric potential energy is increasing. ... Likewise, as you are lowering an object, its gravitational energy is decreasing.
