Specific Charge

• It's the charge per length, or the charge to length ratio of a particular particle, atom or nucleus

• It's the charge per time, or the charge to time ratio of a particular electron

• It's the charge per unit mass, or the charge to mass ratio of a particular particle, atom or nucleus

Ions

• When atoms lose or gain electrons to get a charge

• They are atoms of the same element, with the same atomic number, but different mass number. They have same number of protons, but different number of neutrons

• When electrons lose or gain atoms to get a charge

Isotopes

• When atoms lose or gain electrons to get a charge

• They are atoms of the same element, with the same atomic number, but different mass number. They have same number of protons, but different number of neutrons

• When electrons lose or gain atoms to get a charge
