Question

electron affinity is the measure of

Answer 1

Answer:

Explanation:

Electron affinity is a measure of the energy released when an extra electron is added to an atom. Electron affinities are measured in the gaseous state.

Answer 2

Answer:

• of the energy produced when an atom gains an additional electron

Explanation:

• The amount of energy released when an atom receives an additional electron is known as its electron affinity. The gaseous state is when electron affinities are measured.
• The electron affinity is measured in kJ/mole units.
• When an electron is added to a neutral atom to create a negative ion, the energy of the atom changes (in kJ/mole). This is how electron affinity is defined. Typically, it is expressed as the energy per mole of atoms (in units of kilojoules per mole).
• The energy shift that occurs when an electron is added to a gaseous atom is known as its electron affinity. For instance, the associated energy change is -328 kJ/mol when a fluorine atom gains an electron to create F(g) in the gaseous state.
• While electronegativity is a relative number, electron affinity can be measured experimentally.
