write the short notes . mendeleevs periodic low​

Answer 1

Answer:

hii please mark as brainliest ❤️

Explanation:

The Mendeleev's periodic law states that the physical and chemical properties of the element can be reoccurred according to the atomic weights of the elements arranged in the periodic table. ... The elements will reoccur in a systematic and predictable way in the increasing order of their atomic number.

Answer 2

Answer:

Mendeleev's periodic law states that the properties of elements are the periodic functions of their atomic masses. Elements in each group have similar physical and chemical properties (valency, melting point). The periods are made with elements written in rows of increasing atomic masses. As one goes vertically downwards in a group, the elements show increase in atomic volume. The first two periods are similar to Newlands law of octaves. The feature within each group thus explained Lothar Meyer's observations also.
