As a general rule, while saturated carbon is best attacked by nucleophiles that are neutral compounds, those based on nonmetals far down on the periodic table (e.g. Compare Iodine vs Chlorine of the Periodic Table on all their Facts, Electronic Configuration, Chemical, Physical, Atomic properties. Table of Contents. ), It can possess many charges. In 1913, he photographed the X-ray spectrum of ten elements that held successive places in the Periodic Table. Members of a group typically have similar properties and electron configurations in their outer shell. Look up chemical element names, symbols, atomic masses and other properties, visualize trends, or even test your elements knowledge by playing a periodic table game! The alkaline earth metals (IIA elements) lose two electrons to form a 2+ cation. • how to use the periodic table to predict and model the arrangement of electrons in atoms. It would be hard to overstate its importance as an organising principle in chemistry – all budding chemists become familiar with it from the earliest stages of their education. Iodine is simply identified by its symbol "I" Iodine is the heaviest member in a family of chemical elements called halogens. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. 3. He found that the wavelength (energy) of an X-ray depended on the nuclear charge of an atom. Atomic size Metallic character Non metallic character Ionization potential Melting Point Trends Boiling Point Trends. Iodine Page Two. Elemental iodine has no charge.
