Mendeleev's periodic law.
Answers
Answer:
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.
Explanation:
1. mendeleev organized the periodic table on the basis of atomic masses of elements.
2.when he arranged the 63 elements known at that time in the increasing order of their atomic masses , he found that the chemical and physical properties of elements showed repetation after certain interval.
3.On the basis of this finding, he stated that 'Properties of elements are a periodic function of their atomic masses'. This is known as Mendeleev's periodic law.
