WebPeriod Trends. There are many trends on the periodic table. For example, ionization energy, electronegativity, and of course atomic radius which we will discuss now. Across a period, atomic radii decrease. This is because while the number of electrons increases down the period, they only add to the same main energy level, and therefore do not ... The atomic radius of a chemical element is a measure of the size of its atom, usually the mean or typical distance from the center of the nucleus to the outermost isolated electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic … See more In 1920, shortly after it had become possible to determine the sizes of atoms using X-ray crystallography, it was suggested that all atoms of the same element have the same radii. However, in 1923, when more … See more • Atomic radii of the elements (data page) • Chemical bond • Covalent radius • Bond length See more Widely used definitions of atomic radius include: • Van der Waals radius: In the simplest definition, half the … See more The way the atomic radius varies with increasing atomic number can be explained by the arrangement of electrons in shells of fixed capacity.
