Isotopes of hydrogen are Hydrogen-1 (protium), ‎Hydrogen-2 (deuterium), ‎and Hydrogen-3 (tritium).
Eight hydrogen atoms are necessary (ethyl methyl ether).
Oxygen atoms have a greater electronegativity than hydrogen atoms. Electronegativity is the ability of an atom in a molecule to attract electrons to itself.
the number of helium and hydrogen atoms is the same
1,204428358.1023 atoms of hydrogen
The proportion of hydrogen and oxygen atoms in its molecules.
Hydrogen is a gas. H2 is the description of its molecular structure (2 hydrogen atoms bound together).

No, the elements are not always in the same proportion. For example, two atoms of hydrogen combine with one atom of oxygen to make a single molecule of water. But one atom of hydrogen combines with one atom of fluorine to make a single molecule of hydrogen fluoride. The numbers of atoms involved depends on the number of electrons available in the outer electron clouds of the atoms involved.
The hydrogen molecule, H2, contains two hydrogen atoms and thus, has twice the mass of a single hydrogen atom.
Hydrogen is present in the greatest number of atoms, if that is what is meant by "particles" in the question.

Hydrogen is composed of hydrogen atoms.
Well methane has a chemical structure of CH4 (one carbon surrounded by 4 hydrogen atoms), so for 2 methane you would need a total of 2 carbon atoms and 8 hydrogen atoms (or 4 H2 molecules)
Two hydrogen atoms covalently bonded to one oxygen atom (H2O)
