Composition of the nuclei of two atomic species X and Y are given as under
`{:(,"X",,"Y"),("Protons"" = ","6",,"6"),("Neutrons"" = ","6",,"8"):}`
Give the mass numbers of X and Y. What is the relation between the two species?

Explanation

To solve the question, we will follow these steps:

### Step 1: Identify the number of protons and neutrons for both species.
- For species X:
- Protons = 6
- Neutrons = 6

- For species Y:
