molecules and molecular compounds

Molecules of Compounds - 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 mole..

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 layer, their ..

It is smallest particle (of an element or compound), which is capable of independent existence. Molecules are formed by combination of atoms. Molecules are formed by combination of atoms If the molecule is made up of atoms of the same element it is said to be..

Molecularity - Elementary reactions are classified according to their molecularity. The number of reacting species, which are involved in simultaneous collision to bring about a chemical reaction is called the molecularity of the reaction. In a unimolecular reaction, a..

Atoms and Molecules - 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 propor..

The simplest formula that gives the actual number of atoms of the various elements present in a molecule, of any compound is called its molecular formula. For example, one molecule of water contains two atoms of hydrogen and one atom of oxygen. Therefore, th..

The formula that gives the symbolic representation of the actual number of atoms of various elements present in one molecule of the compound is called the molecular formula. Discrete molecules can be described by this formula. As it represents one molec..

Hybrid Orbitals and Molecular Shapes of Molecules Involving d Orbitals - The Hybridization and molecular shapes of some molecules involving d-orbitals are summarized in the table given belo..

Determination of the Molecular Formula of a Compound - The empirical formula of the compound is written. The empirical formula mass is calculated by adding the atomic masses of all atoms present in the empirical formula. The molecular mass or molar mass is ob..

Empirical formula is the formula of a compound, which shows the simplest whole number ratio between the atoms of the elements in the compound. It does not indicate the actual number of atoms of the elements present but the simplest whole number rat..
