Interpretation:
The element that has two complete
Concept Introduction:
Every atom consists of a nucleus, having protons and neutrons in it, and electrons revolving around the nucleus in their particular shells. These shells consist of subshells or orbitals in which an electron can be found.
The probability density of finding an electron is maximum at a defined region called an orbital.
There is only one orbital in the first shell or first energy level, that is,
In the third shell or third energy level, there are three orbitals
