2. Be, Li, B, C. *(Decreasing order* of ionisation potential ).
3.12,. Cl, F, Br, I. ( *increasing* order of electron affinity. )
4. Na, Cl, Al, O, S.( *decreasing order* of electron affinity. ).
5. F, Cl, Br, I.( *increasing* order of electronegativity ).
6. Cs, Na, Li, K, Rb.( *decreasing order* of electronegativity ).

Answer 2

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

(d) CI, F. Br, I (increasing electron affinity)

I<Br<CI<F

(e) Cs. Na, Li, K, Rb (decreasing electronegativity)

Li>Na>K>Rb>Cs
