Composition of the nuclei of two atomic species X and Y is given as under : `{:(,"X","Y"),("Protons :",6,6),("Neutrons :",6,8):}` Give the mass number of X and Y. What is the relation between the two species and which element or elements they represent ? |

Answer» We know that : Mass numbers = No. of protons + No. of protons + No. of neutrons So, Mass number of X = 6 + 6 = 12 Mass number of Y = 6 + 8 = 14 Thus, the mass number of X is 12 and that of Y is 14 Now, X contain 6 protons, therefore, the atomic number of X is 6. Y contains 6 protons, therefore, the atomic number of Y is also 6. Since X and Y have the same atomic number (of 6) but different mass numbers (of 12 and 14), they are a pair of isotopes. Atomic number 6 is of carbon element. So, both X and Y represent carbon element. |
