Question

difference b/w Shell and subshell ?​

Answer 1

Answer:

In an atom, a shell is a collection of subshells with the same principle quantum number, n . ... Subshells are collections of orbitals which share the same principle quantum number and angular momentum quantum number, l , which is denoted by the letters s , p , d , f , g , h , and so on

Answer 2

Explanation:

The "shell" is the Principal Quantum Number, the number found to the side of a quantum number energy diagram usually as n=(whole number) starting from 1 and going up.

The "sub shells" are the orientations and shapes for your orbitals, going in order by s,p,d,f...
