Question

1) Stable oxidation states for chromium are​

Answer 1

Answer:

The most common oxidation states of chromium are +6, +3, and +2. A few stable compounds of the +5, +4, and +1 states, however, are known. In the +6 oxidation state, the most important species formed by chromium are the chromate, CrO42−, and dichromate,

Answer 2

Answer:

+3 , +6

Explanation:

Cr- [Ar]3d5 4s1

After it has attained a configuration of +3 its electronic configuration becomes [Ar]3d5 4s1

so after it attain +3 oxidation state it become [Ar]3d3 which this makes it half filled stable and after more 3 electron release its oxidation state become +6 and configuration become [Ar] which is inert gas stable compound
