18. An example of an atom that has no

charge is one that has

O A. 3 protons, 2 electrons, and 1 neutron.

O B. 1 proton, 2 electrons, and 3 neutrons.

O C. 2 protons, 2 electrons, and 1 neutron.

O D. 3 protons, 1 electron, and 3 neutrons.

C. 2 protons, 2 electrons, and 1 neutron.

Explanation:

An atom with no charge or neutral charge is an atom with a charge of 0.

Neutrons have no charge so they do not affect it.

Electrons have a negative charge and protons have a positive charge. An equal number of protons and electrons will make the charge neutral.

2 protons, 2 electrons, and 1 neutron.
