Each H atom has one proton in its nucleus.
Nuclear fusion of hyrogen nuclei (protons) to produce helium
no
yes
There are two hydrogen atoms in hydrogen peroxide (H2O2).
in natural resources
non-metal..
NH3Looks like three atoms of hydrogen are in a molecule of ammonia.
the number of hydrogen is 4.0
it bonds with oxygen and fluoride
21
we dont know all of them, but we know hydrogen and helium(which is far into the sun). eventually the sun will run out of fuel (we guess about 5 billion years) and either colapse on itself of super nova energy source: nuclear fusion of hyrogen and helium
carbon mostly and hyrogen
