Valency And Oxidation State
The highest oxidation state shown by a p-block element is generally equal to:
Select the correct option:
Solution
Its group number for groups 13 to 17
For p-block elements in groups 13 to 17, the valence shell has ns2 np1 to ns2 np5 electrons. The maximum positive oxidation state corresponds to participation of all valence electrons and is commonly equal to group number (13 represented as +3, 14 as +4, etc.). This trend explains highest oxidation states across the p-block.

Correct Answer:
Its group number for groups 13 to 17
For p-block elements in groups 13 to 17, the valence shell has ns2 np1 to ns2 np5 electrons. The maximum positive oxidation state corresponds to participation of all valence electrons and is commonly equal to group number (13 represented as +3, 14 as +4, etc.). This trend explains highest oxidation states across the p-block.
