Question

1. Distribute the electrons in different shells of
calcium element​

Answer 1

Answer:

The arrangement and distribution of electrons in different orbits was given by Bohr and Bury. The arrangement of electrons in different shells and sub-shells is known as the electronic configuration of a particular element. ... Similarly, L shell is the second shell and it can hold up to 2(2) = 8 electrons.

A calcium atom has 20 electrons. Two are in the first shell, eight in the second shell, eight in the third shell, and two in the fourth shell.
