which subatomic particle is not found in the nucleus of the atom?
○ proton
○ neutron
○ electron

Explanation:

First Question (Subatomic particles contributing to atom's charge)

Protons have a positive charge, electrons have a negative charge, and neutrons are neutral. So electrons and protons contribute to the atom's charge. Neutrons do not contribute to charge.

The nucleus of an atom contains protons and neutrons. Electrons orbit the nucleus in electron clouds and are not found in the nucleus.

Answer:

C. electron and proton

Second Question (Subatomic particle not in nucleus)
