Arrangement of electrons in an atom and the the periodic table
An electron is stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids. This definition is according to Wikipedia . Therefore, it is obvious that electrons have something to do with electricity and atoms. The arrangement of electrons may be looked at from two points; the periodic table or in an atom. A periodictable is a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns. An atom is the most fundamental or the basic unit of a chemical element. The arrangement of electrons in a periodic table is done according to their size, mass and atomic numbers. You can learn this by watching a presentation on the same from The arrangement of electrons in the periodic table clip . Basically, the electronic structure of an element determines its position in a per...
