Question

5.
The orbits in an atom are numbered by -
(A) 100, 200, 300 ......
(C)1,2,3,4
(B) 10, 20, 30......
(D) 5,10,15 ..​

Answer 1

In the quantum-mechanical version of the Bohr atomic model, each of the allowed electron orbits is assigned a quantum number n that runs from 1 (for the orbit closest to the nucleus) to infinity (for orbits very far from the nucleus). All of the orbitals that have the same value of n make up a shell.
