Question

Using the periodic table, explain the difference between hydrogen, deuterium, and tritium - i.e. hydrogen-1, hydrogen-2, and hydrogen-3.

A)
Allotropes vary in their number of protons - so they contain 1, 2, and 3 protons, respectively.


B)
The atoms deviate in their number of photons - so they contain 1, 2, and 3 photons, respectively.


C)
Isotopes differ only in their number of neutrons - so they contain 0, 1, and 2 neutrons, respectively.


D)
These configurations diverge in their number of electrons - so they contain 1, 2, and 3 electrons, respectively.
