Charge of an ion

  1. Jan 19, 2015 #1
    The charge of a single proton is the elementary charge of 1.6 * 10^-19 C, and the charge of an electron is the negative of the elementary charge, which is -1.6 * 10^-19 C.

    In an electroneutral atom or molecule, there are just as many protons as there are electrons, and so the net charge is 0 C.

    But an ion either loses or gains electrons. For example, an ion with a +1 charge has lost one electron.

    But does this "+1" charge mean that the ion has a charge of 1.6 * 10^-19 C, as there is one more proton than electron?

    Thank you.
