Question

Here,NaCl molecule is made up of which of the following ions?
A. $N{{a}^{+}}$and $C{{l}^{-}}$
B. $N{{a}^{-}}$and $C{{l}^{+}}$
C. ${{N}^{+}}$and ${{C}^{-}}$
D. ${{N}^{-}}$and ${{C}^{+}}$

Answer 1

Hint: The charge on any element is going to depend on the electron affinity or electronegativity of the chemical element. If the element is going to have high electronegativity value, then the element is going to carry a negative charge by accepting the electrons from others and vice versa.

Complete answer:
- In the question it is asked to find the ions which are present in the given compound NaCl (sodium chloride).
- The molecular formula of sodium chloride is NaCl.
- We know that the elements which are present in the sodium chloride are sodium and chlorine.
- But we should know the charges which are present on both the elements.
- Means we should know about the electronegativity of both the elements which are present in the sodium chloride.
- We know that sodium is a metal and chlorine is a non-metal.
- So, the sodium is going to lose the electrons very easily and the chlorine is going to accept the electrons very easily.
- Means sodium has less electronegativity value and chlorine has high electronegativity value.
- Therefore, sodium is going to carry a single positive charge on it due to the donation of a single electron.
- Coming to chlorine, it is going to carry a single negative charge due to the acceptance of one electron from the sodium atom.
- Therefore, the elements which are present in the sodium chloride are $N{{a}^{+}}$ and $C{{l}^{-}}$.

The correct option is A.

Note:
The charge on the element is going to give the information about the number of electrons donated or accepted by an atom which is present in a chemical. The charge on the element is very important to know about its property.
