Question

composition of the nuclei of two atomic species X and Y are given as under. Protons= 6 6, neutrons 6 8 . give the number of X and Y. what is the relation between the two species ?
​

Answer 1

Answer:

• X is carbon-12
• Y is carbon-14

Please ask proper questions, the values in your question are confusing.

Here I have assumed that X has 6 protons and 6 neutrons and Y has 6 protons and 8 neutrons

X and Y have atomic number 6, making them a carbon atom

But X has 6 neutrons

• Atomic mass = no.of protons + no.of neutrons

Atomic mass of X=6+6=12u

Atomic mass of Y=6+8=14u

Since X and Y have same atomic number but different atomic masses. Therefore, X and Y are isotopes, differing in the number of neutrons
