To calculate the standard enthalpy change of a compound, one must first ensure that the chemical equation is balanced. The next step is to look up the standard enthalpies of formation of the reactants and products in a standard enthalpy of formation table. Then, the values from the standard...

In this context, it became evident that the chemical behavior of an element was driven by the ground-state electronic configuration, i.e., the distribution of electrons density in space. The probability distributions of the electrons in atoms, the so-called “orbitals”, indicate the regions of...
