Answer:
A. The number of electrons of a neutral atom always equals the number of protons.
Explanation:
Because the atom is neutral, meaning it has no charge, the protons and electrons would therefore have to be the same. Electrons carry a negative charge while protons carry a positive charge. If you had one more electron than proton, you would have a charge of -1. If they are equal, it would have no charge and be named neutral.
