Question

What is the maximum positive oxidation state exhibited by Selenium ($Se$) in its stable compounds (such as in $SeF_6$)?

Prashant Kotian · Accepted Answer

Correct answer: 6. Group 16 elements possess valence electrons. By utilizing empty d-orbitals to expand their octet, elements from Sulphur onwards (including Selenium) can exhibit a maximum positive oxidation state of +6, commonly seen with highly electronegative elements like fluorine.
