Meyer

Definition

Meyer is a surname associated with Julius Lothar Meyer, a German chemist who independently developed a periodic table of elements around the same time as Dmitri Mendeleev. Meyer's work contributed to the understanding of atomic volumes and periodicity in chemical properties.

5 Must Know Facts For Your Next Test

1. Julius Lothar Meyer published his version of the periodic table in 1864, which arranged elements by their atomic volumes.
2. Meyer's periodic table included 28 elements grouped by valence, or their ability to combine with other elements.
3. He demonstrated that the properties of elements are periodic functions of their atomic weights.
4. Meyer is credited for plotting atomic volume against atomic weight, showing periodic trends among elements.
5. His work helped solidify the concept that elements exhibit recurring or 'periodic' chemical properties.

Periodic Table: A tabular arrangement of chemical elements, ordered by their atomic number, electron configuration, and recurring chemical properties.

Atomic Volume: The volume occupied by one mole of atoms of an element, often used to show trends in the periodic table.

Valence: The combining capacity of an element, often determined by the number of electrons it can lose, gain, or share when forming compounds.
