Web15 aug. 2024 · Group 15: General Properties and Reactions. The nitrogen family includes the following compounds: nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi). All Group 15 elements have the electron configuration ns 2 np 3 in their outer shell, where n is equal to the principal quantum number. Web6 apr. 2024 · Variations within a group. Ionisation enthalpy keep on decreasing regularly as we move down a group from one element to the other. On moving down the group, the atomic size increases gradually due to the addition of 1 new principal energy shell at succeeding element. As a result, the distance of the valence electron from the nucleus …
The first ionization enthalpy values (in kJ\/mol) of group 13 …
WebThe 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: Penetration effect Shielding effect Electronic configuration 1. Penetration Effect Web21 aug. 2024 · The first ionization energy DECREASES down a group in the periodic table. The noble gases have the largest ionization energies, reflecting their chemical inertness. Down Group 18, atomic radius and interatomic forces INCREASE resulting in an INCREASED melting point, boiling point, enthalpy of vaporization, and solubility. richa phogat
