The water molecule is made of one oxygen atom and two hydrogen atoms. Chemists have found that the angle between the bonds is 105 degrees. The structural formula shows oxygen in the center with two hydrogen atoms bonded to it. A covalent bond is formed as the electrons are shared between the oxygen and hydrogen atoms due to their differing valences.

1. The water
molecule
The water molecule is built of one atom of oxygen
and two hydrogen atoms.

2. The water molecule is built of one atom of oxygen
and two hydrogen atoms.
Chemists examining the water molecule outlined
the angle between trusses. He is taking out 105 °.
The structural formula of water is following (we
remember that hydrogen is always univalent, and
bivalent oxygen).

3. Oxygen on the last cover
(for valence coating) has 6
electrons (since lies in 16
for group), and hydrogen 1
electron (is in 1 group).
Oxygen is aspiring to it to
build the truss to have eight
(octet) of electrons on the
last cover, and hydrogen 2
electrons, therefore will
create the common couple.
The common electron
couple is moved in the
direction of element which
more valence electrons
have, i.e. in this case
towards oxygen.

4. A polarized covalent bond is
appearing
in the water molecule.
