Question

difference between minimum and maximum oxidation number of Chlorine

Answer 1

I'm not sure but i think it is 6

Answer 2

Answer: The correct answer is +8.

Explanation:

Chlorine is the 17th element of the periodic table having 17 electrons.

The electronic configuration of chlorine is given as: $1s^22s^22p^63s^23p^5$

Chlorine has an incomplete valance shell, so it may gain 1 electron and show an oxidation state of -1. or, it may loose 7 electrons and show an oxidation state of +7.

Example of chlorine atom showing -1 oxidation state is HCl and compound where chlorine shows +7 oxidation state is $HClO_4$

Difference between minimum and maximum oxidation number of Chlorine atom is [+7 - (-1)] = +8.

Hence, the correct answer is +8.
