Which quantum number is responsible for dividing the main shell into subshells and determining the geometric shape of the orbitals?
Q1. Which quantum number is responsible for dividing the main shell into subshells and determining the geometric shape of the orbitals?
Answer: Azimuthal quantum number
Explanation: The azimuthal quantum number 'l' defines subshell shape (s, p, d, f); 'n' defines the main energy level or shell size.
