The maximum number of sub levels, orbitals and electrons in 'N' shell are respectively

Answer:4, 16, 32

Why:

• For shell N → principal quantum number n = 4.
• Number of subshells (sub-levels) = n = 4 → s, p, d, f.
• Number of orbitals in a shell = n² = 4² = 16.
• Maximum electrons in a shell = 2n² = 2×4² = 32.
