The atomic weight of hydrogen is 1,007 94 ± 0,000 07 atomic units of mass.
Hydrogen is the lightest of all elements. Its atomic weight is 1.00794g/mol. Note that since the atomic weight is the average mass of an atom of an element, most hydrogen has an Atomic Mass of 1.
The atomic weight of Hydrogen is: 1.00794
an oxygen and a hydrogen atom do not weight the same
The conventional standard atomic weight of the hydrogen atom is 1,008 amu.
The atomic weight of hydrogen is 1,007 94 ± 0,000 07 atomic units of mass.
Normal hydrogen (atomic weight 1), deuterium (2), and tritium (3).
Hydrogen atom has an atomic weight of approx. 1 and only 1 proton.
The atomic weight (not mass) of hydrogen is: [1,00784; 1,00811]; the conventional value is 1,008. The atomic weight (not mass) of oxygen is: [15,99903; 15,99977]; the conventional value is 15,999.
The smallest atom is hydrogen.
The mass of a hydrogen atom is 1.66 x 10^(-27) kg. Further, any atomic weight can be derived by dividing its molar mass by Avogardro's number.
The difference between a hydrogen atom and atomic hydrogen is that the "hydrogen atom" represents one atom of the chemical element hydrogen. Atomic hydrogen are isolated hydrogen atoms.
Atomic weight is a unit of measure whose unity value is that of the mass of a Hydrogen atom "1".

Hydrogen atoms are the smallest known elements, and therefore smaller than oxygen atoms (according to atomic weight and atomic mass).
