these were daltons concepts
this has a negative charge (-)
very small and light
travels in orbits around the nucleus
electron
this has a positive charge (+)
located in the nucleus
large, much more mass than the electron
proton
this has (0) charge
located in the nucleus
large, about the same amount of mass as the protons
neutron
where are the electrons?
the electron cloud
where are the protons and neutrons?
in the nucleus
