The Periodic Table: Properties of Groups and Periods

1. The Periodic Table: Properties of Groups and Periods

In the late 1800s, Russian chemist Dmitri Mendeleev created the periodic table by organizing elements by their atomic weight in increasing order. Learn about Mendeleev, discover how the elements on the periodic table are organized, and explore the properties of periods and groups.

Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table

2. Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table

The size of an atom is determined by the distance of the valence electrons from the nucleus. Learn about atomic and ionic radii trends among groups on the periodic table, and how to predict the relative size of an atom based on where it is located on the periodic table.

Ionization Energy: Trends Among Groups and Periods of the Periodic Table

3. Ionization Energy: Trends Among Groups and Periods of the Periodic Table

Ionization energy is the amount of energy needed to remove an electron from an atom. On the periodic table, as atoms increase in size, the amount of energy needed to remove an electron decreases. Learn about ionization energy and how to identify ionization trends on the periodic table.

Electronegativity: Trends Among Groups and Periods of the Periodic Table

4. Electronegativity: Trends Among Groups and Periods of the Periodic Table

Electronegativity measures an atom's tendency to attract a bonding pair of electrons. Explore electronegativity and its trends among groups and periods in the periodic table and discover why some elements are more electronegative than others.
