Question

Quantum Numbers set of a valence electron in a neutral atom is n = 3, l = 0, ml
= 0, ms
= +
1
2 .
Write the name of the element ?

Answer 1

Answer:

Quantum numbers are n=3, l=1, ml=0, ms=±1/2. This set of quantum numbers represents the last electron to be added to complete the ground state electron configuration of an element. From the quantum numbers, we can say that the last electron enters 3p orbital.
