For example, since two isotopes of chlorine have atomic masses equal to 34.980 and 36.977, the mass numbers are rounded off to 35 and 37 respectively. $^_H$Number of protons = 1 Number of electrons = 1 Number of neutrons = 0 The hydrogen element has atoms with mass number 1, 2 and 3 i.e., $^_H$ , $^_H$ & $^_H$.

After bringing the mysterious object home, the pensioner alerted the authorities about his discovery of a shiny lump of metal.

All atoms have a certain value of mass number which is derived as follows.

Hence, the sum of number of proton and neutron is known as mass number.

According to Berlin historian Rainer Karlsch in his book , German scientists carried out three nuclear weapons tests just before the end of the Second World War.

However, Mr Karlsch’s theory was discredited by Gerald Kirchner of Germany’s Federal Office for Radiation Protection.
