Covalent bond between oxygen and hydrogen in water. Intermoleculat hydrogen bond between water molecules.
A hydrogen bond attracts one water molecule to another.
A water (H2O) molecule is held together by covalent bonds. Since oxygen has a higer electronegativity than hydrogen, the bonding electron pairs tend towards the oxygen atom, m…aking the oxygen atom a slight negative pole and the hydrogen atoms positive poles. With the additional V shape of the molecule that comes from oxygen's free electron pairs, the slightly polar bonds make the molecule a dipole with the negative pole on oxygen's side and the positive pole in the center between the hydrogen atoms. (This polarity is why a stream of water can be manipulated with a magnet.) The H2O molecule does not conduct electricity as there are no delocalised electrons.

I assume you are reffering to hydrogen bonding. a water molecule has polarity indicated by delta positive or delta negative (d+, d-) where the oxygen atom is d- and the two hy…drogens are d+. If for example you have two water molecules a hydrogen bond could form between a hydrogen of one atom and the oxygen of the other since the d- is attracted to the d+. Hydrogen bonds are relativly weak, however when many are combined this interaction between two substances can be very strong.
2 bonds -- 2 atoms of hydrogen 1 atom of Oxygen
Oxygen holds electrons more tightly than hydrogen does, and the net charge is zero
hydrogen bond bonds water molecules with other water molecules.
The intermolecular forces between water molecules are hydrogen bonds, a special (and much stronger) version of dipole-dipole bonds.
There is 1 molecule of water in a molecule of water. That 1 molecule is comprised of 1 Oxygen atom and 2 Hydrogen atoms.
