    the students that the atomic number is equal to the number of protons, which is equal to the number of electrons, and it written at the top of the sheet. Atomic mass is equal to the number of protons plus the number of neutrons, so they can find the number of neutrons by subtracting the number of protons from the atomic mass.

In 1932, Irène and Frédéric Joliot-Curie showed that this ray can eject protons when it hits paraffin or H-containing compounds. The question arose that how mass less photon could eject protons which are 1836 times heavier than electrons. So the ejected rays in bombardment of beryllium with alpha particles cannot be photon.
