Atoms and Molecules - Laws of Chemical Combination With the development of more scientific ideas on elements, compounds and mixtures, people began to probe into how and why substances react. French chemist A. Lavoisier laid the foundation to the scientific investigatio..

Formation of Molecule Atoms of most of the elements do not exist independently. They either form molecules or ions. An atom having a charge on it is called an ion. When an atom loses or gains charge, it gets converted into a positively or negati..

Atoms and Molecules - Chemical Formulae Every chemical substance is known by a specific name. But these names can sometimes be cumbersome, confusing and not provide sufficient information about its chemical composition. To overcome this, each chemical compound is repre..

A molecule of a compound consists of two or more atoms of different elements joined together in a fixed ratio. Examples: CuSO 4 contains Cu - 1 atom, S - 1 atom, O - 4 atoms A chemical formula represents the composition of a moleculeh..

With a considerable decrease in the earth's temperature over thousands of years, the atoms of different elements came together at random and formed inorganic molecules. Since the lighter elements (hydrogen, oxygen, carbon and nitrogen) were the most abundant in the outermost lay..

The smallest particle of an element, which may or may not have independent existence is called an atom, while the smallest particle of a substance which is capable of independent existence is called a molecule. Molecules are classified as homoatomic and heteroatomic. H..
