Interpretation:
The reason why the first ionization energy of chlorine is greater than sulfur while the second ionization energy are nearly same has to be given.
Concept Introduction:
Ionization energy:
The ionization energy of an atom is the amount of energy required to remove an electron from the gaseous form of that atom or ion.
Example:
As moving across the period the atomic radius decreases therefore the outer electrons are closer to the nucleus and more strongly held by the nucleus and thus it requires a lot of energy to remove the outermost electron.
Second Ionization energy:
The energy required to remove a second electron from a singly charged gaseous cation is called as second ionization energy.
Example:
The second ionization energy of sodium is
The second ionization energy is almost ten times greater than the first ionization energy because the number of electrons causing repulsions is reduced.
