Answer:
The atoms are isotopes of each other
Explanation:
- Two atoms are said to be isotopes of each other if they have same atomic number Z (which corresponds to the number of protons) but different mass number A (which corresponds to the sum of protons and neutrons in the nucleus).
For atom A, we have:
Z = 10 (10 protons)
A = 10+12 = 22 (10 protons + 12 neutrons)
For atom B, we have:
Z = 10 (10 protons)
A = 10+10 = 20 (10 protons + 10 neutrons)
The two atoms have same atomic number Z but different mass number A, so they are isotopes of each other.
