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.
Actually, thermodynamic entropy increase in chemistry is dependent on two factors. It is enabled by the inherent motional energy of molecules above 0 K (that also can arise from bond energy change in a reaction).hereâ¦now you know more about âwhat entropy really isâ than most beginning students have known for the past century! Entropy in a heating process is just a measure of the motional energy of molecules from hotter surroundings being transferred (reversibly) to a cooler system divided by the T at which it is transferred.
