Question

which of the following halogen does always show oxidation state -1 a)F b)Cl c)Br d)I

Answer 1

I think all of them show oxidation state -1

hope it helps

Answer 2

Explanation:

As halogen are also known as group 17 elements and all the elements present in this group have 7 valence electrons.

Therefore, each element of this group needs to gain one electron in order to complete its octet.

As we known that when a neutral atom gain an electron then it shows an oxidation state or charge of -1.

Since, F, Cl, Br, and I are all elements of halogen group and needs to gain one electron to completely fill its orbital.

Therefore, we can conclude that F, Cl, Br and I all show an oxidation state of -1.
