Vedclass · Answer

(B) Isoelectronic species contain the same number of electrons.$Be^{2+}$ has an atomic number of $4$,so $Be^{2+}$ contains $4 - 2 = 2$ electrons.Among the given options:$H^{+}$ contains $1 - 1 = 0$ electrons.$Li^{+}$ has an atomic number of $3$,so $Li^{+}$ contains $3 - 1 = 2$ electrons.$Na^{+}$ has an atomic number of $11$,so $Na^{+}$ contains $11 - 1 = 10$ electrons.$Mg^{2+}$ has an atomic number of $12$,so $Mg^{2+}$ contains $12 - 2 = 10$ electrons.Since $Li^{+}$ has $2$ electrons,it is isoelectronic with $Be^{2+}$.

$Be^{2+}$ is isoelectronic with which of the following ions?
