an Atom
1 of 35
what are the 3 subatomic particles atoms can be split into
protons, electrons and neutrons
2 of 35
what is the mass charge and location of a neutron
mass= 1 charge= 0 location= nucleus
3 of 35
what is the mass charge and location of a proton
mass= 1 charge= +1 location= nucleus
4 of 35
