What's that?

Can't understand.

Answer 2

Answer:In quantum mechanics, the principal quantum number (symbolized n) is one of four quantum numbers assigned to all electrons in an atom to describe that electron's state. Its values are natural numbers (from 1) making it a discrete variable.

Explanation:The principal quantum number 'n' represents orbit number hence, determine the size of orbitals. The principal quantum numbers are represented by the letters 'K, L, M, N' or equal to 1, 2, 3, 4 etc.

The maximum number of electrons that can accomodate in a principal energy shell is given by 2n2.
