Question

3. Composition of the nuclei of two atomic Species X and Y care
under as
X protons: 6 neutron: 6
Y protons: 6 neutrons: 8
Give the mass number of X and Y. What is the relation between the two species?​

Answer 1

mass no. of x = 12

mass no. of x = 14

Answer 2

Answer:

Mass No. of X = 12,

Mass No. of Y = 14.

Explanation:

Mass no. = No. of protons +No. of neutrons

So, Mass no. of X=6+6

So, Mass no. of X=12

Also, Mass no. of Y=6+8

So, Mass no. of Y = 14

Now, as the no. of protons are equal in both elements and the no. of neutrons are different;

So, these elements are isotopes to each other.
