How do water molecules move away from their H-O-H configuration to become new molecules?

The water molecules move away from their H-O-H configuration to become new molecules as the weak hydrogen bonds are constantly being broken and re-formed.

A water molecule is composed of two atoms of hydrogen and one atom of oxygen. Oxygen shares one of its outer electrons with each of two hydrogen atoms, and each of the two hydrogen atoms share their only electrons.

A water molecule is called a dipolar molecule because of the sharing of the electrons the oxygen side becomes slightly negatively charged and the hydrogen side becomes slightly positively charged. The positively charged side of one water molecule is attracted to the negatively charged side of another water molecule and the two molecules are held together by a weak hydrogen bond. At the temperature range of seawater, the weak hydrogen bonds are constantly being broken and re-formed.

A water molecule is consists of two hydrogen atom, each bound to the central oxygen atom through a covalent chemical bond.

Water molecules can form new molecules by moving away from their H-O-H configuration due to thermal motions and rotations. Thermal motions and rotations break the individual hydrogen bonds and change the  H-O-H configuration influenced by the temperature and pressure.

You use the atomic number to find out how many protons and neutrons there are in the atom. you use the atomic mass to find out how many protons and electrons there are in the atom.
