Electrical Engineering 2020 with Gill’s electronic theory of magnetism 1964

It will be explained why Gill’s electronic theory of magnetism 1964 should replace Maxwell’s dipole theory of magnetism 1873 and its equations

Natural reaction orbitals for characterizing electron transfer responsive to nuclear coordinate displacement

Natural reaction orbital (NRO) is proposed as a new concept for analyzing chemical reactions from the viewpoint of the electronic theory. The pair of the occupied and virtual NROs that...

On the study of D. I. Mendeleev Periodical Law and the modern periodical system of chemical elements in the school chemistry course

The article is dedicated to the 150th anniversary of D. I. Mendeleev’s periodical law, which establishes the dependence of changes in the properties of simple and complex substances on the atomic mass of elements. The main aspects of the study of this topic in the school course of chemistry on the basis of historical facts and information, as well as its further development in the light of electronic theory of the structure of matter are considered. Modern Periodical system of chemical elements on the basis of principles used by scientists and existing ideas about electronic structure of atoms is modeled for pupils. The periodic law is a reflection of the frequency with which electrons fill the energy levels of currently known 118 chemical elements.
