Electrons are not factored into atomic mass because:

• They are so small their mass is negligible
• They're not in the nucleus
• They're too big
• They move so quickly their mass is zero

What does the nucleus of an atom contain?

• Electrons and neutrons
• Protons and neutrons
• Neutrinos and positrons
• DNA and RN
