What does the atomic number mean?
The atomic number is the number of protons there are in the atom
How do you tell how many neutrons there are in an atom?
Atomic Mass= number of protons+ number of neutrons+
What is the Mass and charge of a proton
Mass=1 Charge= +1
What is the Mass and charge of a Neutron
Mass=1 Charge=0
What is the Mass and charge of a electron
Mass=1/2000 Charge=-1
What is the max number of electrons in shells 1,2,3
2,8,8
