One way in which a molecule of hydrogen and a molecule of oxygen differ is in their chemical formula. A molecule of hydrogen consists of two hydrogen atoms (H2), whereas a molecule of oxygen consists of two oxygen atoms (O2).
A hydrogen bond is the type of bond that attracts an oxygen and hydrogen molecule. In a hydrogen bond, the hydrogen atom from one molecule is attracted to the electronegative oxygen atom of another molecule.
Oxygen and Hydrogen
Hydrogen bonds are found between water molecules. These bonds are formed between the oxygen atom of one water molecule and a hydrogen atom of another water molecule.
The bonding between oxygen and hydrogen in the water molecule is a covalent bond. This bond involves the sharing of electrons between the oxygen and hydrogen atoms, resulting in a stable molecule. The oxygen atom attracts electrons more strongly than the hydrogen atoms, creating a polar molecule with partial positive and negative charges.
These are termed to be 'covalent bonds'.
Hydrogen bonds are weaker than covalent bonds. The bond between hydrogen and oxygen in a water molecule is a covalent bond, caused by the sharing of electron pairs between the two atoms. Hydrogen bonds are formed between a hydrogen atom of one molecule and an electronegative atom (like oxygen or nitrogen) of another molecule, and are weaker than covalent bonds.
Oxygen atoms. The hydrogen bond is a weak attraction between a slightly positive hydrogen atom and a slightly negative oxygen atom within the water molecule. This bond gives water its unique properties such as high boiling and melting points.

In water and many other compounds hydrogen and oxygen are held by covalent bonds.Between water molecules and between other polar molecules hydrogen of one molecule and oxygen of a different molecule are held by hydrogen bonds.
A hydrogen bond is the type of bond that attracts an oxygen and hydrogen molecule. In a hydrogen bond, the hydrogen atom from one molecule is attracted to the electronegative oxygen atom of another molecule.
In one water molecule, you have the slightly negatively charged oxygen side, and then you have the slightly positive hydrogen end. Because of this, the negative oxygen attracts positive hydrogens and vice versa in separate water molecules. This is where the hydrogen bonds are made.
Hydrogen bonding is usually formed between one lone pair of electrons of the oxygen atom of one water molecule and the hydrogen atom of another water molecule. Hydrogen bonding forms as a result of electro-negativity difference between oxygen atom and hydrogen, with oxygen being more electro-negative.
Under normal conditions, an oxygen molecule, which contains two oxygen atoms, does not attach to two hydrogen atoms. In a water molecule, which consists of two hydrogen atoms and one oxygen atom, both covalent bonds between oxygen and hydrogen are polar, with the oxygen end of the bond more often negative than either of the hydrogen ends.
polar covalent,
Oxygen has a valence of 2 in a water molecule, while hydrogen has a valence of 1. This allows for the formation of two covalent bonds between the oxygen and the two hydrogen atoms in water (H2O).
