Question

ii) Arrange the following as per instructions given in the brackets:
x Mg, CI, Na, S, Si (Decreasing order of atomic size)
2) Cs, Na, Li, K, Rb (Increasing Metallic character)
3) Na, K, CI, S, Si (increasing ionisation potential)​

Answer 1

The following are arranged as per instructions given in the brackets:

(a) Mg, Cl. Na, S, Si (decreasing order of atomic)

Na>Mg>S>Si>Cl

(b) Cs, Na, Li, K, Rb (increasing metallic character)

Li<Na<K<Rb<Cs

(c) Na, K, CI, S. Si increasing ionisation potential)

K<Na<Si<S<CI
