A = #""_5^11B#
B = #""_5^12B#
C = #""_6^12C#

Explanation:

Both atoms A and B are Boron because they have 5 protons while atom C is Carbon because it has 6 protons.

The difference between atoms A and B is that they are each different isotopes of Boron. This means that they each have a different number of neutrons, and therefore, different masses.
