PERIODIC TABLE PERIODIC TABLE Charles Janet developed the periodic table in 1928. How the periodic table is organized: Charles Janet’s periodic table was organized according all elements that had been discovering before 1928 according to the orbital filling. It also structures the electrons in ascending atomic order Describe the information the periodic table contains: DISADVANTAGE: * The periodic table has a rough tarnation from metal to none-metal. DISADVANTAGE: * The periodic

CIS Chem 12/10/12 Unnecessary Title that’s bold‚ italicized‚ and underlined. The periodic table is a chart of elements set up on the bias of atomic numbers‚ chemical properties‚ and their electron configurations. The elements of this chart are organized in families/groups and periods. The word periodic refers to the way the table is ordered‚ which is in periods and families/groups‚ and it looks like this: The green ones are the non-metals‚ the blue ones are alkali metals‚ the red

devised an early form of periodic table‚ which he called the telluric helix. | John Newlands | Classified the 56 elements that had been discovered at the time into eleven groups which were based on similar physical properties. He also noted that many pairs of similar elements existed which differed by some multiple of eight in mass number‚ and was the first person to assign them an atomic number. | Dmitri Mendeleev | The first scientist to make a periodic table much like the one we use today.

Electrons Have you ever wondered exactly how the elements on the periodic table are organized‚ what the groups on the periodic table mean‚ and how electrons work in an atom‚ compound‚ and chemical bond? The way elements are organized on a periodic table has to do with the characteristics that they hold. There are groups‚ periods‚ compound formation and color coordination in a periodic table. The periodic table is organized in many ways. As stated by Chem4kids.com‚ "Each element is placed
