If velocity of an electron in 1st orbit of H atom is V. what will be the velocity of 3rd orbit of Li+2 **(A) V(B) v/3(C) 3 V(D) 9V

If velocity of an electron in 1st orbit of H atom is V. what will be t

1.	If velocity of an electron in 1st orbit of H atom is V. what will be the velocity of 3rd orbit of Li+2 **(A) V(B) v/3(C) 3 V(D) 9V
Answer» V of H 2⊕ = nh2πZe 2 or V α nZ ∴ V H 2⊕ α 1 (Z = 1, N = 1)V of Li 2+ α 33 α 1 (Z = 3, n = 3)Therefore, velocity of e − in the third orbit of Li 2+ is the same velocity of an e − in the first orbit of H atom
