Richard abegg chemist biography of donald

In , Abegg was appointed a full professor. Abegg's primary research interests lay in physical and inorganic chemistry. He studied diffusion in salt solutions and the electrical conductivity of molten salts. In , with G. Based on this principle, he developed the theory of electrovalence between and According to this theory, ions possess valence equal to their charge.

Each element exhibits two maximum valences: positive and negative. One valence is more typical normal valence , while the other is termed counter valence. He also made the distinction between normal valence and contravalence.

He found that the sum of these two valences always comes to eight, a rule that is now known as Abegg's rule. Contents move to sidebar hide. Article Talk. Read Edit View history. Tools Tools.

Books by Abegg [ edit ]. See also [ edit ]. Abegg introduced the concept of the electro-affinity into chemistry and made the basis for the handbook of the inorganic chemistry — In , Abegg formulated the valence rule, after which the highest positive and highest negative electro-valence of an element yields 8 altogether. This is called Abegg's rule.
