Question

What charge would an ion have if it had more electrons than protong?

A. It would be neutral, since electrons would be outside the nucleus.
B. It would have a net positive charge.
C. It would have no charge.
D. It would have a net negative charge.

Answer 1

D. It would have a net negative charge

Step-by-step explanation:

In an atom, there are electrons, protons and neutrons collectively called SUBATOMIC PARTICLES. The charge of an atom is determined by the number of electrons and protons in that atom. A neutral or uncharged atom possess the same number of electrons and protons.

The charge can thus be calculated as follows:

Charge of atom = no. of protons - no. of electrons.

Hence, when the number of electrons in an atom is higher than that of the protons, it means that the atom has gained negatively charged electrons, making that atom have a net negative charge. For example, In an atom that contains 10 protons and 11 electrons, the charge of that atom will be (10 - 11) = -1. The net charge of that atom will be -1, which is NEGATIVE.
