-1 only for F
Other elements could have -1 to +7 depending on the compound
The halogens (group 17) have an oxidation number of -1, though the halogens below fluorine can have other oxidation numbers as well. Hydrogen can also have an oxidation number of -1 when it forms hydrides.
There are some numbers. Every element shows -1 number.
Because they require one electron to complete their octet
You are asking about group 12. Generally they shows 14 as the oxidation number.
Chlorine is in group 17. It easily accepts an electron from another element to fill its valence shell. As it takes one electron, its oxidation number changes to -1.
-1 is most common, though oxidation number up to +7 are known (except for fluorine)
The halogens (group 17) have an oxidation number of -1, though the halogens below fluorine can have other oxidation numbers as well. Hydrogen can also have an oxidation number of -1 when it forms hydrides.

Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
Group 1 elements have +1 oxidation number (except for hydrogen) All group 2 elements have +2 oxidation number Fluoride ion always has -1
Groups 1 and 2 are +1 and +2 respectivelly.. Group 3-12 have variable oxidation numbers - they are the so-called transition metals. Group 14-17 have variable oxidation numbers -even group 18- has- there are a number of different compounds of Xe for example. Group 1 and 2 have some strange compounds such as Cs11O3 . A better question might be which group doesn't have variable oxidation numbers!
