Who discovered modern periodic law?
Dmitri Mendeleev
In 1869, Russian chemist Dmitri Mendeleev created the framework that became the modern periodic table, leaving gaps for elements that were yet to be discovered. While arranging the elements according to their atomic weight, if he found that they did not fit into the group he would rearrange them.
Which observation led to the development of the modern periodic law?
1864. English chemist John Newlands noticed that, if the elements were arranged in order of atomic weight, there was a periodic similarity every 7 elements. He proposed his ‘law of octaves’ – similar to the octaves of music.
Who is the father of modern periodic law?
Figure 3.2. 2: Dmitri Mendeleev, the father of the modern periodic table.
Who is known as the father of the modern periodical?
General Science ↪ Dmitri Mendeleev is known as the father of modern periodic table .
Who is the father of modern periodic table and why?
↪ Dmitri Mendeleev is known as the father of modern periodic table . He proposed the atomic mass law and divided the whole table in 7 periods and 8 groups according to their physical and chemical properties .
Who is known as the father of periodic table of elements?
Dmitri Mendeleev, Russian in full Dmitry Ivanovich Mendeleyev, (born January 27 (February 8, New Style), 1834, Tobolsk, Siberia, Russian Empire—died January 20 (February 2), 1907, St. Petersburg, Russia), Russian chemist who developed the periodic classification of the elements.
Who is called the father of modern periodic table?

Periodic table/Inventors
Internet search giant Google has dedicated a Doodle to Russian chemist Dmitri Mendeleev on his 182nd birth anniversary. Born on February 8, 1834, Mendeleev is popularly known as the “Father of Periodic Table”.
Who is known as the father of the modern periodic?
Who is the father of new modern periodic table?
Dmitri Mendeleev is often referred to as the Father of the Periodic Table. He called his table or matrix, “the Periodic System”.
How did Henry Moseley contribute to the modern periodic law?
This observation led to the development of modern periodic law. Modern Periodic Law In 1913, a British Physicist Henry Moseley showed that the atomic number is a more fundamental property of an element than its atomic weight. This observation led to the development of modern periodic law.
Who was the inventor of the periodic table?
Nevertheless, the basis of the modern periodic table was well established and even used to predict the properties of undiscovered elements long before the concept of the atomic number was developed. Ask most chemists who discovered the periodic table and you will almost certainly get the answer Dmitri Mendeleev.
Why is the periodic law important to chemistry?
Periodic law is recognized as one of chemistry’s most important concepts. While dealing with the chemical elements, their properties, and their chemical reactions, each chemist makes use of Periodic Law, whether consciously or not. The development of the modern periodic table was driven by periodic law.
How did Mendeleev contribute to the periodic table?
The table below shows the example of Gallium, which Mendeleev called eka-aluminium, because it was the element after aluminium. Scandium and Germanium were the other two elements discovered by 1886, and helped to cement the reputation of Mendeleev’s periodic table. The final triumph of Mendeleev’s work was slightly unexpected.
