This textbook uses conventional current, and anyone who intends to study electronics in an academic or professional environment should learn to naturally think about electric current as something that flows from higher voltage to lower voltage.”.

Electron theory states all matter is comprised of molecules, which in turn are comprised of atoms, which are again comprised of protons, neutrons and electrons. A molecule is the smallest part of matter which can exist by itself and contains one or more atoms.
MODERN ELECTRONIC STRUCTURE THEORY: . Electron Correlation. In the previous lecture, we covered all the ingredients necessary to choose a good atomic orbital basis set. In the present lecture, we will discuss the other half of accurate electronic structure calculations: how we compute the energy.
The electron is the fundamental negative charge (-) of electricity and revolves around the nucleus, or center, of the atom in concentric orbits, or shells. The proton is the fundamental positive charge (+) of electricity and is located in the nucleus.
The nature of electricity can be easily explained by the electron theory of matter. This theory states that all substances whether solid, liquid or gas is composed of small particles called molecules .
Electric current is defined as a stream of charged particles—like electrons or ions—moving through a conductor or space. It measures how fast electric charge flows through a medium over time. The symbol for electric current in formulas is “I” or “i”. The unit for current is the ampere (A).
Electricity and Atomic Structure - Generators use a magnet to get electrons moving. Learn about the relationship between electricity and magnetism and how generators help create a steady flow of electrons.
Electricity is the movement of electrons between atoms. Electrons usually remain a constant distance from the atom's nucleus in precise shells. The shell closest to the nucleus can hold two electrons. The next shell can hold up to eight. The outer shells can hold even more.

Electron theory explains that electrical conduction happens when electrons move from atom to atom in a material. This movement, triggered by voltage (force), creates an electric current. Therefore, electron theory is essential to understanding how and why electricity flows.
