Answer 2

What do you mean by ionization enthalpy?

$\rightarrow$ Ionization enthalpy is defined as the amount of energy required to remove an electron from an isolated gaseous atom and its ground state.

• the ionization enthalpy is expressed in units of KJ mol-¹

• second ionization enthalpy as the energy required to remove the second most loosely bound electron.

Hope it helps you dear.
