Ionization Energy and Electron Affinity

The electron affinity of an element is the energy given off when a neutral atom in the gas phase gains an extra electron to form a negatively charged ion. A fluorine atom in the gas phase, for example, gives off energy when it gains an electron to form a fluoride ion. F ( g) + e - F - ( g) Ho = …

Ionization Energy

Hence, this will have the highest ionization energy. Among, [Ne] 3s 2 3p 1 and [Ne] 3s 2 3p 2, nuclear charge is more in [Ne] 3s 2 3p 2 increasing the attraction of the nucleus on the s-electron. So, this will have higher ionization energy than [Ne] 3s 2 3p 1. The order of increasing order of ionization energy of the atoms is –
