The history of the periodic table reflects over two centuries of growth in the understanding of the chemical and physical properties of the elements, with major contributions made by Antoine-Laurent de Lavoisier, Johann Wolfgang Döbereiner, John Newlands, Julius Lothar Meyer, Dmitri Mendeleev, Glenn T. Seaborg, and others.

2021年2月7日 · The periodic table provides information about the atomic structure of the elements and the chemical similarities or dissimilarities between them. Scientists use the table to study chemicals and design experiments.

In 1869 Dmitri Mendeleev created the first variation of the periodic table as we know it today. He was the first person to arrange the elements by increasing atomic mass and leave spaces open for the elements that had not yet been discovered.

The periodic table was invented by Russian chemist Dmitri Mendeleev in 1869. However, prior to Mendeleev, chemists had been pondering for decades how to classify the elements. Beginning in 1789, Antoine Lavoisier began classifying elements by their properties.

The modern periodic table differs in some ways from Mendeleev’s original version. It contains more than 40 additional elements, and its rows are longer instead of being squeezed under one another in staggered columns.

By 1809, a total of 47 elements had been discovered, and by 1863, 56 were known. As the number of known elements grew, scientists began to recognize patterns in their properties and began to devise ways to classify them.

2023年4月12日 · The periodic table achieved its modern form through the work of the German chemist Julius Lothar Meyer (1830–1895) and the Russian chemist Dimitri Mendeleev (1834–1907), both of whom focused on the relationships between atomic mass and various physical and chemical properties.
