Question

define ionisation potential and electron affinity balance chemical equation​

Answer 1

Answer:

The ionization energy or ionization potential is the energy necessary to remove an electron from the neutral atom. The electron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion

Answer 2

Answer:

Ionization energy is the energy required to remove an electron away from an atom, which can be written as IE. ... Electron affinity, on the other hand, is the energy released when an electron is added to the atom. On the periodic table, electron affinity usually decreases down a group, and increases across a period.
