A positively charged substance is brought near the ion. What will most likely happen and why?

The ion will attract the substance because it has lost two electrons.

The ion will attract the substance because it has lost an electron.

The ion will repel the substance because it has lost two electrons.

The ion will repel the substance because it has lost an electron.

The ion will repel the substance because it has lost two electrons.

Explanation:

The information about the ion reveals that the atom is made up of 12 positive particles and 10 negative particles.

Positive particles in an atom are called protons and the negative ones are called electrons.

In a neutral atom that has not lost or gained any electrons, the number of protons and electrons are equal.

For a charged atom called an ion, it has either lost or gained additional electrons.

Now, we are given an atom with 12 protons and 10 electrons. The number of particles are not the same. Here the number of protons outweighs that of electrons by 2. This makes the atom positvely charged which implies a loss of two electrons.

For a normal/neutral atom the number of protons and electrons should be the same i. e 12. But the atoms lost two electrons to bring the electron tally to 10. The atom is positively charged in this regard.

If a positively charged substance is brought near it, there will be repulsion. Generally, according to coulomb's law " like charges repel each other and unlike charges attracts".

When the positive charge is brought near the positively charged ion, a repulsive force is established.
