The correct pair of electron affinity order is

Which one of the following arrangements represents the correct order of electron gain enthalpy (with negative sign) of the given atomic species?

Fluorine has lower electron affinity than chlorine because of

When an electron is added to elements of group $16$ and $17$ in $n = 2$ and $n = 3$ shells,which case experiences less electron-electron repulsion and why?

Electron gain enthalpy values $(\Delta_{eg} H)$ (in $kJ \ mol^{-1}$) of elements $X$,$Y$ and $Z$ are $-349$,$-200$ and $-295$ respectively. $X$,$Y$ and $Z$ are respectively

In which of the following processes is the highest energy absorbed?
