How atom exist |
| Answer» Atoms exist\xa0in free states in the form of molecule. ... Molecules may be formed by the combination of\xa0atoms\xa0of two or more different elements. For example molecule of water. It is formed by the combination of two\xa0atoms\xa0of hydrogen and one\xa0atom\xa0of oxygen.\xa0Atoms\xa0are not able to\xa0exist independently. All the elements on the far right side of the periodic table (inert or noble gas)\xa0atoms can exist independently\xa0because they all fulfil the octet rule. They\xa0do\xa0not need bond to become stable. ... A molecule is comprised of two or more chemically bonded\xa0atoms. It is estimated that there are between10^78 to 10^82\xa0atoms\xa0in the known, observable universe. In layman\'s terms, that works out to between ten quadrillion vigintillion and one-hundred thousand quadrillion vigintillion\xa0atoms. | |
