Question

Number of protons, neutrons and electrons en
tour species A, B, X and Y are respectively
6, 6, 6; 7,7,7;6, 8, 6, and 9, 10, 10. Give
symbolic representation of each species
and tell which of them are isotopes
and which are isobar?​

Answer 1

Answer:

Atomic mass=number of protons+number of neutrons

Atomic mass of X = 6+6=12

Atomic mass of Y =6+8=14

Both X and Y have same atomic number but different atomic mass number so they are isotopes.
