The electrons are found in shells or orbits that surround the nucleus of an atom
Protons and neutrons are found in the nucleus . They group in the center of the atom
Why not search it up and figure it out and then write it how you would?
The answer to this question would be: electron
When atoms bind together, that mean they shared at least one electron. The electron is located on the outer side of the atoms so the electron from an atom can collide with other electrons from another atom. The protons and neutron can't make bind because it was in the middle of the atom and won't collide each other.
