Going from K ...

Question

Going from K shell to N shell, how can KE decrease as on going farther away from the nucleus the electron rotates faster due to lesser hold of the nucleus?

Open in App

Solution

$K . E . = \frac{K Z e^{2}}{2 r}$

$K . E . α \frac{1}{r}$
As we move from K to N, r increases and KE decreases.

Q. Why shell near nucleus have minimum energy whereas farther away shell has maximum energy?

Energy of the shells decreases with increase in distance from nucleus.

Q. In an electron capture, electron from K shell falls into a nucleus to undergo beta decay.

on absorbing a neutron goes over to

. This nucleus emits an electron to go over to neptunium which on further emitting an electron goes over to plutonium. The plutonium nucleus can be expressed as:

Q. The nuclear charge actually experienced by an electron is termed as the effective nuclear charge. The effective nuclear charge Z* actually depends on the type of shell and orbital in which electron is actually present. The relative extent to which the various orbitals penetrate the electron clouds of other orbitals is

The phenomenon in which penultimate shell electrons act as screen or shield in between nucleus and valence shell electrons and thereby reducing nuclear charge is known as shielding effect. The penultimate shell electrons repel the valence shell electron to keep them loosely held with the nucleus. It is thus evident that more is the shielding effect, lesser is the effective nuclear charge and lesser is the ionization energy.
