Question: Who Proposed Modern Periodic Law?

Who proposed modern periodic law what was the basis of arranging the elements in it?

Henry Moseleymodern periodic law is proposed firstly by Henry Moseley in 1913.

The basis of arranging elements in modern periodic table is the electronic configuration.

modern periodic law states that elements should tale place in a table according to their atomic number..

Who is the first father of chemistry?

Antoine LavoisierIf you are asked to identify the Father of Chemistry for a homework assignment, your best answer probably is Antoine Lavoisier. Lavoisier wrote the book Elements of Chemistry (1787).

What is Moseley’s periodic law?

Moseley found that there was a relationship between wavelength and atomic number. … Mendeleev and Moseley are credited with being most responsible for the modern periodic law: When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties.

What is the difference between Mendeleev periodic law and modern periodic law?

Mendeleev’s periodic table is, based on relation of properties of elements as dependent on the atomic weight of element. But Modern periodic table considers atomic number as the fundamental property that decides the properties of elements. Modern periodic table does correct defects of the Mendeleev’s periodic table.

What are the disadvantages of modern periodic table?

What are the disadvantages of modern periodic table?Position of hydrogen is not satisfactory, it can be placed either in group I or 17 group of the first period.It fails to accommodate lathanides and actinides in the main body of the periodic table. These are kept separately at the bottom of the periodic table.

What is the modern periodic law?

The modern periodic table is based on the periodic law: “The chemical properties of elements are a periodic function of their atomic number.” Let’s see how is this different from Mendeleev’s periodic table and how this solves for its predecessor’s limitations.

Who is the father of modern periodic law?

What is the name of modern periodic table?

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends.

Who proposed law of triads?

Johann Dobereinertriad: In 1829, a German chemist, Johann Dobereiner (1780-1849), placed various groups of three elements into groups called triads. One such triad was lithium, sodium, and potassium. Triads were based on both physical as well as chemical properties.

Can modern periodic table solve all problems?

No, the modern periodic table cannot solve all the problem. Explanation: Modern periodic table is a better alternative than the other form of the periodic table.

How is modern periodic law proposed?

Hint: The Scientist who invented modern periodic law was an English physicist. … Dmitri Ivanovich Mendeleev proposed the periodic law behind his periodic table compiling. This law states that when the elements are listed in order of increasing atomic weights, their properties vary periodically.

Who proposed the modern periodic table?

Dimitri Ivanovich MendeleevYet historians typically consider one event as marking the formal birth of the modern periodic table: on February 17, 1869, a Russian professor of chemistry, Dimitri Ivanovich Mendeleev, completed the first of his numerous periodic charts.
