Atoms exist in free states in the form of molecule. ... Molecules may be formed by the combination of atoms of two or more different elements. For example molecule of water. It is formed by the combination of two atoms of hydrogen and one atom of oxygen. Atoms are not able to exist independently. All the elements on the far right side of the periodic table (inert or noble gas) atoms can exist independently because they all fulfil the octet rule. They do not need bond to become stable. ... A molecule is comprised of two or more chemically bonded atoms. It is estimated that there are between10^78 to 10^82 atoms in the known, observable universe. In layman's terms, that works out to between ten quadrillion vigintillion and one-hundred thousand quadrillion vigintillion atoms.
