Detail

Following are the details for the electronic configuration of the Krypton;

first shell

first shell of krypton contains

only one subshell, 1s, in the first shell, and it has two electrons.

second shell

Two subshells present in the second shell: 2s and 2p.

The 2s subshell has two electrons,
while the 2p subshell has six.

third shell

Third shell contains two subshells namely 3s and 3p.

The 3s subshell has two electrons,

while the 3p subshell has six.

fourth shell

fourth shell contain three sub shell:

4s, 3d, and 4p.

Electronic distribution

two electrons in the 4s subshell,
ten in the 3d subshell,
and six in the 4p subshell.
