Question

what is the unit of measurement for ionization energy as shown in the graph? calories kilojoules per mole joules watts

Explanation:

Ionization energy is the energy required to remove an electron from a gaseous atom or ion. It is typically expressed per mole of atoms or ions, and the SI - derived unit for energy is the joule. Commonly, it is given in kilojoules per mole. Calories are a non - SI unit of energy mainly used in nutrition. Joules alone don't account for the molar quantity usually associated with ionization energy measurements. Watts is a unit of power, not energy.

Answer:

B. Kilojoules per mole
