1.	Composition of the nuclei of two atomic species X and Y are given as under `{:(,"X",,"Y"),("Protons"" = ","6",,"6"),("Neutrons"" = ","6",,"8"):}` Give the mass numbers of X and Y. What is the relation between the two species?
Answer» Mass number of X = Number of Photons + Number of neturens = 6+6= 12 Mass number of Y = Number of photons + number of neutron = 6 +8 = 14
