Question

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

Give the mass numbers of X & Y.
What is the relation between the two species?​

Answer 1

Answer:

mass no:

Mass number of X = No. of protons + No. of neutrons

= 6 + 6 = 12

Mass number of Y = No. of protons + No. of neutrons

= 6 + 8 = 14.

relation:

The 2 atomic species X and Y have  same atomic number and a different mass number.therefore , they are isotopes.
