AMg, Al, Si
BArgon, helium, neon
CProtium, deuterium, tritium
DH+, H, H- in the standard view
Answer & Solution
Correct answer: C. Protium, deuterium, tritium
1. Hydrogen has three naturally occurring isotopes.
2. Protium has 0 neutrons, deuterium has 1 neutron, tritium has 2 neutrons.
3. All share atomic number 1.
4. So the isotopes are protium, deuterium and tritium.
