... So what constitutes a chemical bond? A bond is formed when electrons from two atoms interact with each other and their atoms become joined. The electrons that interact with each other are VALENCE ELECTRONS, the ones that reside in the outermost electron shell of an atom. There are two main types of ...

In the hopping region, σac (ω), decreases smoothly as In content increases from 6 % up to 16 %, then it increases with a faster rate from 16% to 21% In content. This may be attributed to the increase of ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
