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.
The entropy of the system, which is Î´Q/T, increases by Î´Q/273K. The heat Î´Q for this process is the energy required to change water from the solid state to the liquid state, and is called the enthalpy of fusion, i.e. Î´H for ice fusion.ntropy is a function of the state of a system, and has a value determined by the state variables of the system. The concept of entropy is central to the second law of thermodynamics.
