How Do I Show the Atomic Radii Groups on a Periodic Table?
The atomic radius is the distance from the center of an atom to the outside of its electron cloud. Each element of the periodic table has its own atomic radius, and some have larger atomic radii than others. The groups of the periodic table refer to the columns of the table. Each periodic column is a separate group. In order to show the atomic radii groups, understand the periodic trend for atomic radius, write in the estimated sizes of the atomic radii for each element, and color each group a different color. Examine the periodic trend for atomic radii. The atomic radius for each element generally decreases from left to right on the periodic table. The reason for this is that, from left to right, the value of the electronegativity increases. Electronegativity is the attraction an atom has for its electrons. The atoms to the right of the periodic table are more likely to attract electrons because they only need a small amount of electrons in order to achieve stability. The atomic radiu
