Could someone break down the difference between ionization energy and electron affinity?

[April Meza 3K]

Electron affinity gives the amount of energy released when an atom gains an electron. The ionization energy is the amount of energy required to remove an electron from an atom.

[kendal mccarthy]

electron affinity is the atoms affinity or how much an atom wants an electron and the energy it gives off when it obtains an electron. Ionization energy is the energy it takes to take away an electron from an atom. Usually, these trends follow a similar pathway on the periodic table as atoms who have a high electron affinity have a high ionization energy and vice versa.

[Nathan Rothschild_2D]

Will we have to calculate either electron affinity or ionization energy or simply just know what they are? and if we do have to calculate them how do we do so?

[Brian J Cheng 1I]

We will not need to know how to calculate the exact values in ionization energy or electronegativity; however, we will need to know what they mean and their respective periodic trends. We'll also need to know how they apply to bonding (i.e. the atom with the highest electronegativity prefers a negative formal charge, and the atom with the lowest IE or highest electronegativity is usually the central atom in a Lewis diagram).

[ZainAlrawi_1J]

The ionization energy is the amount of energy that is required to remove an electron from an atom, while an atom's electron affinity is the amount of energy released or spent when an electron is added to an atom.

[Katie Bart 1I]

Ionization energy and electron affinity do follow the same trends on the periodic table (even though they are two separate concepts).

[AmyL_3L]

Ionization energy is the energy required to remove an electron from an ion or gaseous atom, whereas electron affinity is the amount of energy released when an electron is added to an atom to form an anion. Both periodic trends, however, are the same.

[Cynthia Rodas 4H]

Ionization energy refers to the minimum amount of energy needed to remove an electron whereas electron affinity is the amount of energy released when an electron is added.
