Question

2. Element showing different oxidation states is (Li, Mn, CI) (1)

Answer 1

Answer:

(a) F is more electronegative as it belongs to group 17;7 and can show only negative oxidation state of –1.

(b) Caesium is highly electropositive and can show only +1 oxidation state as it has only one electron in its valence shell.

(c) I has 7 electrons in its valence shell and can, therefore, exhibit an oxidation state of –1, However since Iodine has empty d orbitals it can also exhibit different oxidation state like +1,+3,+5,+7.

(d) Neon is an inert gas and hence do not exhibit any oxidation state.
