Question

3. The composition of two atoms X and Y are as follows:
X - 6 protons, 6 neutrons
Y 6 protons, 8 neutrons
(a) Write the mass of X and Y.
(b) What is the relation between X and Y ?​

Answer 1

Answer:

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

a) Mass no. of X = 6 + 6 = 12

Mass no. of Y = 6 + 8 = 14

b) As no. of protons are same in X and Y but Mass no. varies, they are isomers to each other.

hope this will help you
