From Chemical Potential to Electronegativity Relationships

As based on the chemical potential measure within the density functional formalism, further the various implications of the electronegativity concept will be present, since the direct inter-relationship by the sign changing. 

For example, with the aid of the chemical potential, a new form for expressing the total energies of the electronic system as density functional can be written (Parr et al., 1978)  

Expression (3.105) may be formalized under the total differential form  

Moreover, with unfolding the total differential for the expression g[p] 

Further chemical modeling reactivity may be performed with the homogeneous functionals assumption, as in next formalized.
