(A) The number of electrons in the ion $M^{2+}$ is $2 + 8 + 14 = 24$.Since the ion is $M^{2+}$,the neutral atom $M$ has $24 + 2 = 26$ electrons.Therefore,the atomic number $(Z)$ of the element is $26$.The mass number $(A)$ is given as $56$.The number of neutrons $(n)$ is calculated as $n = A - Z$.$n = 56 - 26 = 30$.
