II Review l Constants 1 Periodic The periodic table lists all known elements by their masses and groups elements by their properties. Within the periodic table, there are many properties of the elements that have periodic trends as we move down the groups in the table or across the periods. Part A Rank the following elements by atomic radius. Rank from largest to smallest atomic radius. To rank items as equivalent, overlap them. ► View Available Hint(s) Reset Help Largest...

4. The periodic table is organized to show "periodic" traits of elements. Name at least three properties of elements in the table are traits that follow a periodic pattern.
12. Give the general trend in the periodic table (period, group) for the main group elements (Groups I-VIII) for a) sizes of atoms, cations, anions (same charge) b) ionization energies c) electron affinities d) electronegativities
In the Periodic Table below, shade all the elements for which the neutral atom has a valence electron configuration of ns np, where n stands for an integer Li Be Na Mg
