Some important facts about atomic structure: Electrons in a non-excited atom are motionless. Space inside of atom is not empty, but filled with space matter. There are three factors that determine the electron configuration in a multi-electron atom. They are a) attraction from the nucleus, b) repulsion between electrons (repulsion between electrons in a shell and between electrons in the inner and outer shells). c) buoyant force exerted by space matter. An atom has two types of shells; 1) Electron shells: - Regions where the electrons are configured in an atom, when the atom in non-excited state.2) Transitory shells: - Possible regions, which the electrons can jump from their electron shells, when they are in an excited state. Structure of electron: Electron has a standing- electric field and magnetic field in right angle regardless of any kind of its motions and act as a tiny bar magnet with a negative charge. In an atom, the electric fields of its electrons will be directed to the nucleus and magnetic fields will be horizontal to the nucleus. Magnetic field will be created in the following circumstances: A charged particle (positive/negative) has magnetic property and act as a small magnet. When charged particles are aligned in a single way in a material, a magnetic field will be created around that material. For example, when electrons are flowing through a conductor, all electrons will be aligned in a single way. This alignment of flowing electrons creates a ...
