They are isotopes of hydrogen
You have left out the third example
Hydrogen weighs 1 amu (proton, electron)
Deuterium weighs 2 amu (proton, neutron, electron)
Tritium weighs 3 amu (proton, 2 neutrons, electron)
When taking into account their relative occurence in nature, the average molecular weight of hydrogen is 1.00079 amu (in other words, Deuterium and Tritium are almost non-existent) and keep in mind, hydrogen is usually found in the molecular state of H2

Regular hydrogen has one proton and weighs 1 amu. An isotope with a neutron also weighs 2 amu and is sometimes called deuterium. There is another isotope with 2 neutrons, weighing 3 amu called tritium. The atomic mass given on the periodic table has a mass with decimals to show these isotopes and their relative amount. The mass given is a weighted average.

the answer is D) The atomic mass listed on maximum periodic tables for hydrogen (a million.008 amu) is an overall of the three isotopes of hydrogen: Hydrogen (a million proton, a million electron) - a million amu Deuterium (a million proton, a million electron, a million neutron) - 2 amu Tritium (a million proton, a million electron, 2 neutrons) - 3amu To get the cost a million.008, you would possibly want to take each and every isotope's mass and multiply it by employing the percentage that that isotope occurs in the international, then upload those 3 numbers. So: 1amu*(a%) + 2amu*(b%) + 3amu*(c%) = a million.008 amu the position a + b + c = one hundred%

these are different isotopes of hydrogen. The second one is called deuterium which all formed at the big bang when the universe was created 13.5 billion years ago

ISOTOPES!!!!
A normal atom contains the same amount of neutron and protons. An isotope contains a different amount of neutrons vs. protons.

isotopes
both these molecules are isotopes to each other containing the same number of electrons but different number of neutrons
