Question

On the basis of electronic configuration if ion x3- has 14 electrons then no. of electrons in x2+ are

Answer 1

no. of electrons in ×2+ are 19

Answer 2

Explanation:

When an atom gain electrons then it acquires a negative charge whereas when an atom loses electrons then it acquires a positive charge.

Since it is given that there are 14 electrons in $X^{3-}$ ion so this means that in X there will be in total 11 electrons.

Also, it is known that when an atom is neutral then there will be equal number of protons and electrons.

Hence, in a $X^{2+}$ ion there will be 9 electrons.
