Question

where is an atom is the mass located

Answer 1

I think in the nucleus, since electrons are more more lighter than protons and neutrons

Answer 2

Most of the mass is concentrated in the nucleus. The nucleus is made up of neutrons and protons. Outside the nucleus is where the electrons stay. the neutrons and protons are the heaviest of the three types of particles, and the electrons are nearly weightless. the majority of the mass is concentrated in the nucleus. @kitzia_needs_help
