Elements Affecting The Periodic Table

The organization of the periodic table takes account of many different factors. All elements in the table display a periodic trend. Electron configuration and properties also affect the periodic table. The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons. The periodic table depicts atomic radius by configuring them from smallest to largest as you move down the table. Ionic radius is the radius of an atom's ion. Although neither atoms nor ions have sharp boundaries, they are sometimes treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice. The periodic table organizes the ionic radius in the groups. as you go down the table the ionic radius of the atoms gets bigger. In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular

They have specific properties that set them aside from the other elements. All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metals; and have at least one basic oxide. Metalloids are metallic-looking brittle solids that are either semiconductor or exist in semiconducting forms and have amphoteric or weakly acidic oxides. Typical nonmetals have a dull, colored or colorless appearance; are brittle when solid; are poor conductors of heat and electricity, and have acidic oxides. Most or some elements in each category share a range of other properties; a few elements have properties that are either anomalous given their category, or otherwise
