Atomic numbers of oxygen and sulphur are 8 and 16 respectively. Oxygen atom has 6 neutrons and sulphur atom has 16 neutrons. Find out the mass number of oxygen and sulphur atom.

Q.:- Atomic numbers of oxygen and sulphur are 8 and 16 respectively. Oxygen atom has 6 neutrons and sulphur atom has 16 neutrons. Find out the mass number of oxygen and sulphur atom.

 

Answer:-

Mass number of oxygen atom = No. of protons + No. of neutrons

                                               = 8+8=16
Mass number of sulphur = No. of protons + No. of neutron
                                       = 16+16=32
