chemical bonding and molecular structure

Chemical Bonding and Molecular Structure The smallest particle of element is atom and the smallest particle in a compound is molecule. The force or the binding that keeps the atoms in the molecule combined during the formation of molecule is called chemical bonding. The concepts like that of Kossel-Lewis, VSEPR principle, valence bond theory, molecular … Read more

Valency and Chemical Bonding

Valency Valency of an element is a measure of its combining power with other atoms when it forms chemical compounds or Molecules. The combining power, or affinity of an atom of a given element is determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in … Read more
