Define: Electron
In response to a question, a student stated that in an atom, the number of protons is greater than the number of neutrons, which in turn is greater than the number of electrons. Do you agree with the statement? Justify your answer.
Assertion: Proton can be defined as a hydrogen ion (H+).
Reason: These photons are produced when one electron is removed from one hydrogen atom.
An atom is electrically neutral. Give reason.
