Question

Define ionization energy and electron affinity .explain it please friend ​

Answer 1

$\huge\boxed{Answer}$

Ionization energy is the energy needed to remove an electron from an atom or an ion at its gaseous state.

Electron affinity is the energy released or absorbed when an electron is added to an atom or ion at its gaseous state.

Hope it helps you...

Answer 2

Answer:

ionization energy:

ionization energy or ionisation energy, is the minimum amount of energy required to remove the most loosely bound electron of an isolated neutral gaseous atom or molecule.

Electron affinity:

The electron affinity of an atom or molecule is defined as the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion.

Similarities/differences

Ionisation energy is the energy to remove an electron from an atom. The first ionisation energy is the energy to remove one electron from a neutral atom, to make an ion with a +1 charge. ... Electron affinity is to do with the energy required to add an electron to a neutral atom
