In ionic bonding, electrons are completely transferred from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. The oppositely charged ions are attracted to each other by electrostatic forces, which are the basis of the ionic bond.
Entropy is a measure of the degree of the spreading and sharing of thermal energy within a system. The entropy of a substance increases with its molecular weight and complexity and with temperature. The entropy also increases as the pressure or concentration becomes smaller.
CY101 T. Pradeep 2007 2 The meaning of entropy: Entropy of mixing Consider that a number of ideal gases are separated which are present in a vessel.Let n i be the number of moles of each gas and V i is the volume it occupies. The total entropy,S 1 = ân i (C v ln T + R ln V i + S i)1 Note the term S i.Y101 T.
