What is the periodic law of present form of periodic table?

The modern periodic law states that the physical and chemical properties of the elements are the periodic functions of their atomic numbers. Scientists arranged elements in increasing order of their atomic numbers from left to right across each row.

How it can be proved that the basic structure of the modern periodic table is based on the electronic configuration of atoms of different elements Class 10?

For example, if the electronic configuration of an element is 2, 1, it means that the element belongs to group I and 2nd period (valence electron is present in the 2nd shell). Thus, the modern periodic table is based on the electronic configuration of the different elements.

What were the basic properties considered by Mendeleev for the classification of elements?

In Mendeleev’s periodic table, elements were arranged on the basis of the fundamental property, atomic mass, and chemical properties.

What element is an element named after one of the United States found in the actinide series?

Because the lanthanide element above it on the periodic table was named europium after Europe, americium (Am, 95) was named after America.

How important is the periodic law?

Periodic Law is considered to be one of the most important concepts in chemistry. Every chemist makes use of Periodic Law, whether consciously or not, when dealing with the chemical elements, their properties, and their chemical reactions. Periodic Law led to the development of the modern periodic table.

What is Mendeleev periodic law and modern periodic law?

Mendeleev’s Periodic Law states that the physical and chemical properties of elements are periodic functions of their atomic weights. On the other hand, the Modern periodic Law states that the physical and chemical properties of elements are periodic functions of their atomic numbers.

How can we prove that the basic structure of modern periodic table?

The group represents the number of valence electrons of the element. The total number of electrons is given by the atomic number. So as a whole we can say that the basic structure of the modern periodic table is the electronic configuration of the elements.

What we’re the properties used by Mendeleev in creating his periodic table?

Explanation:Mendeleev arranged the elements on the basis of their atomic mass. Melting and boiling point were used as the physical characteristics in deciding the position of elements.

How many elements were known when Mendeleev classified the elements?

63 elements
To put some order into his study of chemical elements, Mendeleev made up a set of cards, one for each of the 63 elements known at the time. Mendeleev wrote the atomic weight and the properties of each element on a card.

What element is named after a US state?

Californium is named for the university and state of California, where the element was first made.

What element is named after a country?

Elements which are named after currently existing countries and cities are as: Polonium, named after Poland. Francium and gallium, both named after France. Nihonium, named after Japan.
