An ion X³⁺ is obtained from an element X (atomic mass 27 and atomic number 13). The number of protons, electrons and neutrons in X³⁺ is respectively:

Correct option is B

The answer is (b) 13, 10 and 14.
The atomic number of an element is the number of protons in its nucleus. In this case, the atomic number of element X is 13, so there are 13 protons in the nucleus of X3+.
The charge of an ion is determined by the number of electrons it has compared to the number of protons. In this case, X3+ has a charge of +3, which means that it has lost 3 electrons compared to a neutral atom of X. Therefore, there are 13 - 3 = 10 electrons in X3+.
The mass number of an element is the number of protons and neutrons in its nucleus. In this case, the mass number of element X is 27, so there are 27 - 13 = 14 neutrons in the nucleus of X3+.
