The periodic table was created by chemists, specifically Dmitri Mendeleev in 1869. Mendeleev organized the elements based on their properties and atomic weights to create a system that displayed the periodic trends of elements.
The periodic table was developed by Russian chemist Dmitri Mendeleev in 1869. He arranged the elements based on their atomic mass and chemical properties, revealing repeating patterns in their behavior. Mendeleev's periodic table is a fundamental tool in chemistry for organizing and predicting the properties of elements.
Yes, Mendeleev left gaps in his periodic table for undiscovered elements. He predicted the properties of these missing elements based on the trends in the known elements and their positions in the table. This helped in the discovery of elements such as gallium, scandium, and germanium.

Dmitri Mendeleev was a Russian chemist who is famous for formulating the periodic table of elements, arranging them according to definite trends in their properties. He was born in 1834 and died in 1907.
Mendeleev organized his periodic table by atomic mass and similar chemical properties of elements to recognize patterns and trends. He arranged the elements in horizontal rows and vertical columns based on these properties, allowing him to predict the properties of undiscovered elements.
In 1869, a Russian chemist named Dmitri Mendeleev invented this table to help show trends in the behavior of chemicals.
Dmitri Mendeleev is credited with creating the Periodic Table of Elements in 1869. He arranged elements by increasing atomic weight and noticed periodic trends in their properties which led to the development of the modern periodic table.
The periodic table was created by chemists, specifically Dmitri Mendeleev in 1869. Mendeleev organized the elements based on their properties and atomic weights to create a system that displayed the periodic trends of elements.
The two main factors that led to the widespread acceptance of Mendeleev's periodic table were its accurate prediction of the properties of then-unknown elements and its ability to explain the periodic trends observed in elements. Additionally, Mendeleev's table was able to organize the known elements in a logical and systematic manner, making it easier to understand and use.
A lot of people noticed similar trends, but it took Dmitri Mendeleev to organise them by increasing atomic number and group them by similar characteristics.
