Lothar Meyer (jan 1, 1864 – jan 1, 1864)

Description:

-
Introduction and Basis:
Lothar Meyer was a German chemist who published a periodic table that described the placement of 28 elements in the year 1864. His periodic table arranged the elements into six families according to their valence, which was the first attempt to classify the elements according to this property. His periodic table ordered the elements into groups arranged based on the atomic weights of the elements.

Examples:
The examples for the families which he arranged the elements to according to their valence is for example alkali metals, halogens, noble gases, etc.

Limitations and Comparisons:
Although Meyer's periodic table was a significant advancement, it did have some limitations. Firstly, some of the atomic weights were inaccurate, leading to a few misplaced elements. Secondly, some elements were out of order on the periodic table based on their atomic weights.

Compared to Döbereiner's triads, Lothar Meyer's periodic table covered a wider range of elements and was more systematic. He also grouped elements with similar properties together, like the alkali metals and halogens. Dobereiner noticed that some elements could be grouped into threes with similar traits, while Meyer found a larger, more organized pattern among all the elements.
Meyer's table was a significant improvement over Dobereiner's triads.
