If an atom has one proton and one electron state the charge on the atom. Justify your answer.

A hydrogen atom contains one proton and one electron. It may be assumed that the electron revolves in a circle of radius 0.53 angstrom (1 angstrom = 10^(-10) m and is abbreviated as A) with the proton at the centre. The hydrogen atom is said to be in the ground state in this case. Find the speed of the electron in the ground state of hddrogen atom.

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.
