Elementary Charge: Read or Calculate?

[Ankhen]

Hi. Do there exits equipment that can read the elementary charge of atom? Or do we only know there charge by calculation?
And the same question about there mass

I assume you know about Millikan's Oil Drop Experiment, right?

Do you also know about mass spectometers?

An atom does not have an elementary charge associated with it.
Usually an atom is neutral, so its overall charge is zero.
Some atoms may become positive or negative, when the charge balance is disturbed.
Elementary charge is carried by the components of atoms, protons and neutrons. Each proton has an elementary positive charge and each electron has an elementary negative charge.

Nope, but thanks
