Question

combustion of the nuclei of two atomic species A and B are given asunder
element A. B
protons. 17. 17
neutrons. 18. 20

what are the most number of A and B how are related to each other

Answer 1

Heya !

Here's your answer !!

__________________________

Since the no. of protons is same of both A and B, hence their atomic no. is also same.

Since, their atomic no. is 17, the element is CHLORINE.

The atomic no. of A and B is same but their no. of neutrons is different. Therefore, they are isotopes of the same element that is chlorine.
