See the explanation
Explanation:
Ionization energy is the energy required to remove one electron from an atom of an element in an isolated gaseous state.
Ionization energy always increases ,i.e., second ionization energy is always greater than the first ionization energy.
Mathematically,
The is the energy required to produce one mole of gaseous cations...
Explanation:
The is the energy required to produce one mole of gaseous cations, and one mole of gaseous electrons, from one mole of gaseous element....i.e.
These are extensively tabulated....and, reasonably,
Ionization energy: Minimum amount of energy required to remove an electron from isolated gaseous atom is called ionization energy of that element.
Explanation:
Minimum energy required for this process
So, ionization energy of Na atom is
