Question

what is electron affinity​

Answer 1

Answer:

Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.

Answer 2

Answer:

Electron affinity is the energy change that results from adding an electron to a gaseous atom.

This is a example of electron affinity⬇️

For example, when a fluorine atom in the gaseous state gains an electron to form F⁻(g), the associated energy change is -328 kJ/mol.
