Deuterium (""_1^2H)

Explanation:

Hydrogen-1 (""_1^1H) typically consists of a proton in the nucleus and an electron orbiting it.

Deuterium, or hydrogen-2 (""_1^2H) is an isotope of hydrogen and like hydrogen-1 also has a single proton in the nucleus but also has a single neutron as well. Again, the electron orbits nucleus.
