What two particles make up the nucleus?

The protons and the neutrons make up the nucleus. The protons are equal to the number of electrons and is also the atomic number of that element.


What are the sub atomic particles that make up an atom?

The three subatomic particles that make up an atom are the protons, neutrons, and electrons. The protons are positively charged particles that are located in the atomic nucleus at the center of the atom. The neutrons are particles that have no charge and are also located in the nucleus. The electrons are negatively charged particles that are located in the electron cloud surrounding the nucleus.
