Atomic Number
the mass of an atom
The number of protons in the nucleus of an atom
the total number of protons and neutrons in the nucleus of an atom
same as the electron cloud
Atomic Mass - check all that appy
the number of neutrons
the electron cloud
measured in AMU - atomic mass units
The mass of an atom
Mass Number
a positively charged particle
the total number of protons and neutrons in the nucleus of an atom
The number of electrons minus the number of neutrons

What does APE help you remember
Atomic Mass = # of Protons = # of electrons
Atomic Number = # of Protons = # of electrons
Atomic Particles include Electrons
Atomic Mass is Pretty easy to calculate with Electrons
What does MAN help you remember
Mass Number + Atomic Number = # of Neutrons
Mass Number loves Atomic Number
Mass Number - Atomic Number = No of Neutrons
