Answer: Option (c) is the correct answer.
Explanation:
It is known that sub-atomic particles present in an atom are protons, neutrons and electrons.
It is given that there are 2 positive sub-atomic particles present in the given atom. This means there are 2 protons.
And, it is give that there are 3 negative sub-atomic particles. This means that there are 3 electrons.
Also, when an atom is neutral then there are same number of protons and electrons.
This also shows that the given ion contains a negative charge. As like charges repel each other so, when a negatively charged substance is brought near the ion then there will occur repulsion between them.
Thus, we can conclude that the ion will repel the substance because it has more electrons than protons.
