A large difference between the fourth and fifth ionization energies indicates the presence of
1 4 valence electrons in an atom
2 5 valence electrons in an atom
3 3 valence electrons in an atom
4 8 valence electrons in an atom
Explanation:
After four electrons, ion gets stability so it has great \(\mathrm{IP}_{5}\). It means it has 4 valence electrons.

Arrange the following elements in increasing order of first ionization enthalpy: \({\mathrm{\mathrm{Li}, \mathrm{Be}, \mathrm{B}, \mathrm{C}, \mathrm{N}}}\) Choose the correct answer from the options given below:
The penetration of a 2 s -electron to the nucleus is more than that of a 2 p -electron; hence the \({\mathrm{2 p}}\) electron of boron is more shielded from the nucleus by the inner core of electrons than the 2 s electrons of beryllium. Therefore, it is easier to remove the \({\mathrm{2 p}}\)-electron from boron compared to the removal of a 2 s - electron from beryllium. Thus, boron has a smaller first ionization enthalpy than beryllium. From left to right,i.e, increases. Hence ,the order is \({\mathrm{\mathrm{Li} < \mathrm{B} < \mathrm{Be} < \mathrm{C} < \mathrm{N}}}\).
