Question

explain penetration effect in subshell with example​

Answer 1

Answer:

In other words, penetration depends on the shell (n) and subshell (ml). Forexample, we see that since a 2s electron has more electron density near the nucleus than a 2p electron, it is penetrating the nucleus of the atom more than the 2p electron.

Answer 2

Explanation:

Ionization enthalpy increases as the penetration effect of the electron increases

s> p >d > f

The ionization enthalpy will be more to knock out a s-electron than a p- electron of the same shell ' which in turn ' will be more than that required remove a D-day electron and so on.

It is a well known that in case of multi electron atom, the electron of the s- orbital has the maximum probability Of being found near the nuclear and this probability goes on decreasing in case of p, d and f orbital of the same shell

For example : first ionization enthalpy of aluminum is lower than that of magnesium
