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.
