Q. Number of neutrons in an atom of hydrogen is:
Answer: Zero
Notes: Neutrons are the particles in an atom that have a neutral charge. So, if an atom has equal numbers of electrons and protons, the charges cancel each other out and the atom has a neutral charge. Hydrogen (H) has 1 proton and 1 electron; it does not have any neutron in its nucleus. Therefore its atomic number equals the mass number.
