How are elements arranged in one group
WebThe periodic table is the table that indexes all chemical elements. It is arranged in order of atomic size (Hydrogen, then Helium, then Lithium, etc.) which is determined by the number of protons in the element. The table is subdivided into periods (rows) and groups (columns) of elements that share common characteristics, hence the name "periodic". WebThe elements in the Periodic Table are arranged according to increasing atomic number. As you go horizontally from left to right across a Period in the Periodic Table, you are …
