There are ________ unpaired electrons in the Lewis symbol for a nitride ion.

Anna71 [15]

Answer:

There are no unpaired electrons.

Explanation:

There are no unpaired electrons in the Lewis symbol for a nitride ion( ${ N }^{ 3- }$ ).The nitride ion has a charge of -3. The negative charge on the Nitride ion indicates a gain in electrons . Nitrogen has 5 valence electrons that is the number of electrons that are in its outer shell .The total number of electrons that the nitride ion has is equal to 5+3 = 8 electrons . Electrons usually appear in pairs and obey the octet rule therefore the nitride ion has four electron pairs no unpaired electrons.
