The ionization energy and electronegativity in the periodic table increases across the period and up in the column. Thus, option A is correct.
The ionization energy has been given as the amount of energy required to remove the electron from the outermost shell. The electronegativity has been given as the tendency for the addition of the electron.
The electronegativity and ionization energy has been directly proportional and has been based on the size and attraction towards the electron.
In the periodic table on moving down the group, the size of the atom increases, thereby decrease in the attraction force and increase in ionization energy and electronegativity.
On moving across period, there has been an increase in the electrons in the outermost shell, and increased force. Thus, the electronegativity and ionization energy decreases across the row.
Thus, the ionization energy and electronegativity in the periodic table increases across the period and up in the column. Thus, option A is correct.
