The ionization energy is when an electron is removed, and it is the amount of energy needed to remove it. This electron is the easiest to remove because it is the most loosely bound electron. It could be a valence electron. There is a formula which is X plus energy leads to positive X plus negative e. There are specific trends that are used from this ionization.

They are that the power increases as you move to the right within the period of the periodic table. It will decrease if you move to the bottom of the periodic table. If some ionization energies are reported for element X. All the values are in kJ/mol. The first is 500, and the second is 4560, the third is 6910, the fourth is 9540, and the fifth is 13400. The most likely identity of X is Na.
