A molecule consists of two or more atoms joined, or
bonded, together. Many familiar substances, such
as sugar or water, are made up of molecules.
Molecules are so small that even a small
drop of water contains trillions of them.
All the molecules of a particular compound
(chemically bonded substance) are identical.
Each one has the same number of atoms,
from at least two elements
combined in the same way. The bonds
that hold molecules together form during
chemical reactions but they can be
broken as atoms react with other atoms
and rearrange to form new molecules.
It is not only compounds that can exist
as molecules. Many elements exist as
molecules, too, but all the atoms that
make up these molecules are identical,
such as the pair of oxygen atoms that
make up pure oxygen (O2).
What keeps a molecule together?
Atoms in a molecule are held together by covalent bonds.
These form when atoms share electrons. In every atom, the
electrons are grouped around the nucleus in shells. Each
shell has a certain number of atoms it can hold before it is
full. Atoms are most stable when their outer shell is full,
and sharing electrons is one way to achieve this.
