Question

Composition of the nuclei of two atoms X and Y are given below X. Y Protons = 4. 4
Neutrons = 4. 6 Give mass no. Of x and Y mention the relationship between the two atoms

Answer 1

Answer:

Composition of the nuclei of two atomic species X and Y are given as under Protons 6 6 Neutrons 6 8

Solution : Mass number of X = Number of protons + Number of neutrons = 6 + 6 = 12. Mass number of Y = Number of protons + Number of neutrons = 6 + 8 = 14. These two atomic species X and Y have the same atomic number, but different mass numbers. Hence, they are isotopes.
