Question

The atomic number of an element X is 13.What will be the number of electrons in its ion $X^{34}$

Answer 1

If the atomic number of an element X is $13$.The number of electrons in its ion $x^{3+}$ will be 10. This is because $x^{3+}$ is a positively charged cation. An atom loses electrons from its valence shell and becomes positively charged ion called cation. Here, Atom $X$ loses $3$ electrons and acquires $3+$ charge. therefore the number of electrons lost will be $3$. and the number of electrons in its ion $x^{3+}$ will be $10$.
