The most accurate answer is that atoms are generally neutral because they are made up of an equal number of protons (positively charged) and electrons (negatively charged). The opposite charges of protons and electrons balance each other out, resulting in an overall neutral charge for the atom.
Neutrons are also present in atoms, but they do not have a charge, so they do not contribute to the overall charge of the atom. While it is true that some atoms may have more neutrons than protons and electrons, this does not affect the overall charge of the atom, since neutrons do not have a charge.
It is important to note that there are some cases where atoms are not neutral, such as when they gain or lose electrons to form ions. In these cases, the number of electrons is no longer equal to the number of protons, resulting in a net positive or negative charge for the ion.
