why the atomic mass of hydrogen is not double from their atomic no.?
Anonymous:
actually mass no is the avg of all the isobars' weight. the isotopes of hydrogen have masses such that when their mean mass is taken it gives 1 . also the other 2 answers are right but r the elementary ones

Hey !
Solution :
We know that Atomic Mass of an element equals Number of protons + Number of electrons.
=> Atomic Mass = Number of Protons + Neutrons.
But we know that, Hydrogen being the first element lacks neutrons in it's atomic structure. Hence the mass can be calculated as :
Atomic Mass of Hydrogen = 1 Proton + 0 Neutron
=> Atomic Mass of Hydrogen = 1 g or 1 u
Hope it helped !

the isotopes of hydrogen have varying mass no.s the mass of any element is the avg of all the isotopes' masses. the isotopes pf hydrogen have values such that the mass of hydrogen is 1 [approx.] (1.008).
great
