Periodic Table Characteristics
- The periodic law states that the properties of elements recur periodically when the elements are arranged in order of their atomic numbers.
- Metallic character generally increases from top to bottom and from right to left in the periodic table.
- Trends in the periodic table are characterized by periodic variations in properties, such as atomic radius, electronegativity, and electron affinity, when elements are arranged in order of their atomic numbers.
History of the Periodic Table
- The first generally accepted periodic table was formulated by Dmitri Mendeleev.
