Verified step by step guidance

Identify the element symbol 'D^+' in the image, which represents deuterium, an isotope of hydrogen.

Recall that deuterium has one proton and one neutron in its nucleus.

Since the symbol is 'D^+', it indicates a positive charge, meaning it has lost one electron.

Determine the number of protons: Deuterium has 1 proton.

Determine the number of neutrons: Deuterium has 1 neutron. Determine the number of electrons: Since it is 'D^+', it has 0 electrons.
