As per the Modern periodic law, the physical and chemical properties of elements are periodic functions of their

Write modern periodic law .

"The properties of elements are the periodic functions of their atomic masses"

Observe the following statements. Q I. The physical and chemical properties of elements are periodic functions of their electronic confirguration. Q II. Electronegativity of fluorine is less than the electronegativity of chlorine. Q III. Electropositive nature decreases from top to bottom in a group. The correct answer is

"The law states hat the physical and chemical properties of the elements are periodic functions of their atmic weights ".

The physical and chemical properties of an atom depends on its

A: The properties of elements are the periodic functions of their atomic weights. B: The properties of elements are the periodic functions of their atomic numbers.

The basis of modern periodic law is

PASSAGE - 3 : In modern periodic table there is gradation in the properties of elements. In a period the Ionisation energy, Electron affinity, Electro negativity, Non-Metallic nature increases. In a group the atomic size, metallic nature, reducing properties and densities of elements increases. The pair of elements with equal electro negativities

PASSAGE - 3 : In modern periodic table there is gradation in the properties of elements. In a period the Ionisation energy, Electron affinity, Electro negativity, Non-Metallic nature increases. In a group the atomic size, metallic nature, reducing properties and densities of elements increases. Whic pair of elements have positive electron affinity values
