1.	If n = 6, the correct sequence for filling of electrons will be, ……(a) ns → (n – 2) f → (n – 1) d → np (b) ns → (n – 1) d → (n – 2) f → np (c) ns → (n – 2) f → np → (n – 1) d(d) none of these are correct
Answer» (a) ns \(\rightarrow\) (n – 2) f \(\rightarrow\) (n – l) d \(\rightarrow\) np n = 6 According Aufbau principle, 6s → 4f → 5d → 6p ns → (n – 1) f → (n – 2) d → np.

If n = 6, the correct sequence for filling of electrons will be, ……(a) ns → (n – 2) f → (n – 1) d → np (b) ns → (n – 1) d → (n – 2) f → np (c) ns → (n – 2) f → np → (n – 1) d(d) none of these are correct

Answer»

(a) ns \(\rightarrow\) (n – 2) f \(\rightarrow\) (n – l) d \(\rightarrow\) np

n = 6

According Aufbau principle,

6s → 4f → 5d → 6p

ns → (n – 1) f → (n – 2) d → np.
