Question

Match the following

Column I	Column II
(i) 2s, 3s, 4s, 4d (order of increasing energy )	(a) Bohr model
(ii) Quantum numbers of 2s² electrons $n$ ℓ m s 2 0 0 +1/2 2 0 0 -1/2	(b) Hund’s Rule
(iii)	(c) Pauli’s exclusion
(iv) Principal quantum number “n”	(d) Aufbau principle
	(e) Size of orbit

TestHub · Accepted Answer

(i) → (d) ( n + 1 ) rule (ii) → (c) two electron must have opposite spin (iii) → (b) electron must be spin singly occupied (iv) → (a, e) It was used by Bohr’s and it represent size of orbit .
