Subatomic Particle Charges
•Positive Proton
•Neutral Neutron
•Negative Electron
Where are the electrons
located?
Outside the nucleus in the Electron Cloud.
What is the atomic number?
The number of protons in the nucleus.
What is the atomic mass?
The number of protons and neutrons in the
nucleus.
How do we find/calculate the
number of neutrons in an atom?
Subtract the number of protons from the
atomic mass.
(#neutrons = mass - # protons)
