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.
