A molecule of a compound consists of two or more atoms of different elements joined together in a fixed rati..

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 molecule of the substance in terms..

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 out..

. Metalloids are the elements, which have properties that lie between those of metals and non-metals, e.g., arsenic, antimony, etc. Molecules of elements may consist of single atom, two atoms, or even more. All the hundreds of thousands of compounds existing,..

Atoms and Molecules - 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 o..

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..

Summary The law of conservation of mass states that the masses of the reactants and products remain unchanged. The law of constant proportions states that all pure specimens of a compound always contain the same elements combined together in the same proportion by weight..

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 represented by a chemical formula that give..

Atomicity of a Molecule of an Element - The number of atoms, which constitute one molecule of an element, is called its atomicity. Phosphorus: P 4 - 4 atomicity Sulphur: S 8 - 8 atomicity Oxygen: O 2 - 2 atomicity Recently a different form of carbon - C 6 0 h..

The number of atoms, which constitute one molecule of an element, is called its atomicity. Phosphorus: P 4 - 4 atomicity Sulphur: S 8 - 8 atomicity Oxygen: O 2 - 2 atomicity Recently a different form of carbon - C 6 0 has been discovered. It is named buckminsterfullerene. Depend..
