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". medford rogues scheduleWebIn astronomy, stellar classification is the classification of stars based on their spectral characteristics.
