Question

All stable atoms are made of ____? -positively charged, with the number of protons exceeding the number of electrons/ -negatively charged, with the number of electrons exceeding the number of protons/ -neutral, with the number of protons equaling the number of electrons/ -neutral, with the number of protons equaling the number of electrons, which is equal to the number of neutrons

Answer 1

The answer is the last option. All stable atoms are made of neutral, with the number of protons equaling the number of electrons, which is equal to the number of neutrons. Electrons are negatively charged while the neutrons are positively charged. Equal number of both particles will result to a neutral charge.
