Question

: Which of the following will
P, S, CI, F. Explain your answer.
Electron gain enthalpy generally becomes more negative across a period as we move
to right within a group, electron gain enthalpy becomes less negative down the group
adding an electron to the 2p-orbital leads to greater repulsion than adding an electron to
3p-orbital. Hence, the most negative electron gain enthalpy is of chlorine and the leas
electron gain enthalpy is of phosphorus.
Try Yourself
17. Which among the following elements will have a positive electron gain enthalpy?
B, C, N, O.
18. S has more negative electron gain enthalpy than O why?
ronegativity
negativity of an element is the tendency of an atom to attract the shared pair of electrons
qualitative measure, because unlike ionization enthalpy and electron gain enthalpy whic​
