The number of electrons in element X’s ion X3+ is 10.
Explanation:
- When the atomic number of element X is 13, the no. of electrons in its ion is 10, which is obtained by reducing 3 from 13.
- This can be represented as below: Atomic number = No. of electrons = No. of protons
- So, if an atom has a positive/plus charge of 3, the remaining number of electrons will be 10 (+13-3 = 10).
