Question

Q3:What are quantum numbers?
Write down all the quantum numbers
of 3 shell of iron atom​

Answer 1

Answer:

The set of numbers used to describe the position and energy of the electron in an atom are called quantum numbers. There are four quantum numbers, namely, principal, azimuthal, magnetic and spin quantum numbers. The values of the conserved quantities of a quantum system are given by quantum numbers.

For iron, [Ar]4s23d6 , then n=3 , l=2 (because it is the d orbital), ml is −2 (because you count up one the series from −l to +l six times, for the six electrons in the d subshell) and ms is ±12
