A hydrogen molecule consists of two hydrogen atoms.
There are two atoms of Hydrogen in the molecule.
2 hydrogen atoms and 1 oxygen atom
There are four hydrogen atoms in an ethanal molecule, CH3CHO.
There are three hydrogen atoms in an ammonia molecule.
A molecule consists of many atoms. When you have a hydrogen molecule, or whatever other type of molecule for that matter, you have many hydrogen atoms that make it.
The two atoms share their electrons - so it is a covalent bond ie a shared pair.
There are two atoms of hydrogen in a molecule of H2O2.
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
Hydrogen peroxide is a molecule because it is a combination of atoms with a bond.
2 hydrogen atoms and 1 oxygen atom
A pentane molecule has 5 carbon atoms and 12 hydrogen atoms.
That depends on what kind of sugar you're talking about. Table sugar, or sucrose, has the formula C12H22O11. One molecule of sucrose has 22 hydrogen atoms. Blood sugar, or glucose, has the formula C6H12O6. One molecule of glucose has 12 hydrogen atoms. Other types of sugar have different formulas. If you know the chemical formula, look at the subscript to the right of the H to see how many hydrogen atoms are in one molecule of sugar.
