what happens to chemical bonds during chemical reactions

Atoms of elements combine to form molecules of compounds. This combination can occur in two ways: either by electrovalent bonding or covalent bonding. In all chemical reactions it is the electrons from the outermost shell of an atom that are involved in..

Types of Chemical Reactions - When a chemical reaction occurs how are new substances produced? Do atoms of one element transform themselves into atoms of another element? Do atoms withdraw from the mixture or turn up from elsewhere? Neither of these happ..

Internal Energy - Every substance possesses a definite quantity of energy, under a given set of factors such as chemical nature of the substance, temperature and pressure. The total energy contained in a system or substance is called its internal energy or intrinsic energy. It is represen..

Everyday experience tells us that chemical reactions take place in widely varying rates. Infact rates of various reactions vary from very slow to very fast. Some reactions are so rapid that they occur as soon as the reactants are mixed. For example, the ..

Covalent or metallic bonds, ionic bonds Chemical bonds between atoms in molecules such as H2, CH4, NH3, H2CCH2, N2, Cl2 Electrostatic attraction in salt crystals such as NaCl Inter-molecular forces in a solid and liquid Lewis dot structures - Shape ..
