✒️The law that the properties of the elements are periodic functions of their atomic numbers. Also called Mendeleev's law. (originally) the statement that the chemical and physical properties of the elements recur periodically when the elements are arranged in the order of their atomic weights.

✒️The basic law governing modern periodic table states that the properties of elements are periodic functions of their atomic number.

$\huge\bold\red {Answer♡}$

The statement " Properties of elements are periodic functions of their atomic number" means that if elements are arranged in increasing order of their atomic numbers, then after a fixed interval, properties of elemnets start repeating, it means elements with similar properties fall in a vertical row. Properties of an element are sometimes classed as either chemical or physical. Some properties of an element can be observed only in a collection of atoms or molecules of the element. These properties include color, density, melting point, boiling point, and thermal and electrical conductivity.
