Answer :
Final answer:
Nitrogen and Phosphorus, both non-metals, create negative ions (N³- and P³- respectively) by gaining three electrons to achieve a stable configuration like a noble gas.
Explanation:
The non-metal atoms Nitrogen and Phosphorus found in group 5 of the periodic table form ions with a negative charge. Both Nitrogen and Phosphorus aim to achieve a stable electron configuration similar to the next noble gas in the periodic table by gaining electrons. This results in the formation of anions (negatively charged ions), as a gain of electrons increases the negative charge of the atom. For example, Nitrogen becomes N³- and Phosphorus becomes P³- upon each gaining three electrons.
