Question

in a neutral atom, which atomic particles are equal in number?
a electrons, protons, and neutrons
b protons and neutrons
c protons and electrons
d electrons and neutrons

Explanation:

In a neutral atom, protons carry a positive charge and electrons carry a negative charge. For the atom to be neutral, the number of positive - charged protons must equal the number of negative - charged electrons. Neutrons have no charge and their number is not necessarily equal to that of protons or electrons in a neutral atom.

Answer:

C. protons and electrons
