Periodic Table Trends by Ella

What is Atomic Radii?

             By definition atomic Radii something that looks like the radius of a circle, where the center of the circle is the nucleus and the out side of the circle is the electron. As you begin to move across or down the periodic table, trends begging to blend together that help explain how atomic radii change.

This is a representation, since Li (lithium) is closer to the nucleus the atomic Radiis are bigger than the Ne (neon) that is in farther then the nucleus.

 What is an Ionic Radii?

                Ionic radius, is the radius of an atom's ion. Neither of this atoms or ions have specific boundaries, they are sometimes treated as if they were hard spheres with radii such that the total of the ionic radii of the cation (+) and anion (-)  gives the distance between the ions on the nucleus.
