Answer :
Final answer:
When nitrogen satisfies the octet rule, it forms a charge of -3.
Explanation:
When nitrogen satisfies the octet rule, it typically forms a charge of -3. Nitrogen has five electrons in its outermost electron shell, but to achieve a stable electron configuration, it needs a total of eight electrons in its outer shell. To reach this octet configuration, nitrogen tends to gain three electrons when forming compounds, resulting in a net charge of -3.
This is commonly observed in compounds like ammonia, where nitrogen shares three of its electrons with three hydrogen atoms, effectively filling its outer shell and attaining a stable electronic configuration with eight electrons, albeit with a negative charge.
