WebFirst, Nitrogen is gas, but as you move down, there is a significant increase in the metallic character of the elements. Nitrogen and Phosphorus are non-metals, Arsenic and Antimony are metalloids and Bismuth is a metal. These changes can be attributed to the decrease in Ionization enthalpy and increase in atomic size.

The ionization enthalpy of an element can be defined as the amount of energy required to remove an electron from an isolated gaseous atom in its gaseous state.Ionization enthalpy depends on the following factors: 1. Penetration effect 2. Shielding effect 3. Electronic configuration See more Penetration means the proximity of an electron in an orbital to the nucleus. For each shell and subshell, it can be observed as the relative density of electrons near the nucleus of an atom. Now if we look into … See more The shielding effect can be defined as the effect in which the inner electrons develop a shield for the electrons in outer shells which does not let the appropriate nuclear charge towards the … See more Elements having half-filled and fully filled orbitals are stable. So if we will try to remove an electron from these orbitals, then it will make them less stable. Hence, more amount of … See more WebAnswer (1 of 3): Ionisation enthalpy of the group 13 elements is not regular.
