Based on their definitions, electron affinity could be considered the opposite of

Explanation:

Ionization energy is the energy released when an electron from the outermost shell of an atom is given out. The opposite is the energy required to put an electron in the outer most orbit of an atom. This energy is termed as electron affinity.

The electron affinity (Eea) 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. ... In other words, the enthalpy change and the electron affinity differ by a negative sign.

This is the amount of energy needed to pull an electron away from the atom in the gaseous state, or the tendency of an atom to give up electrons. This is conceptually the opposite of electron affinity.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
