Vedclass · Answer

(A) For the ion ${}^{14}_{7}N^{3-}$, the atomic number $(Z)$ is $7$, which represents the number of protons. Therefore, protons = $7$.The mass number $(A)$ is $14$. The number of neutrons is calculated as $A - Z = 14 - 7 = 7$.Since the ion has a charge of $-3$, it means the nitrogen atom has gained $3$ electrons. The number of electrons = (Atomic number) + (Magnitude of negative charge) = $7 + 3 = 10$.Thus, the number of protons, neutrons, and electrons are $7, 7, 10$ respectively.

Calculate the number of protons, neutrons and electrons respectively in ${}^{14}_{7}N^{3-}$.
