Question

An element has a valency of +3 what will be the formulae of its nitride.

Answer 1

Explanation

Valency: is the combining power of an element.

• Elements in the same group of the periodic table have the same valency.
• An element has a valency of +3 what will be the formulae of its nitride MN
• The valency of an element is related to how many electrons are in the outer shell.
• The M has a +3 +ve charge needs a -3 -ve charge to balanced
• Nitrogen electronic configuration is [He] 2s² 2p³
• Nitrogen shows 3 oxidation state 3 and forms MN.
