Question

Write short note on Mendleev's periodic law

Answer 1

HEY FRND..☛☺☜⛤
☛⛤⛤☺In 18690 Russian chemist Dmitri Mendeleev Published a Periodic Table and corresponding periodic law of 63 elements known at that time
☛☺⛤Mendeleev’s Periodic Law states that “The Physical and Chemical Properties of the elements are periodic functions of their atomic weights.”
⛤⛤☛☺Mendeleev not only predicted the existence of these elements and called them Eka-Aluminium, Eka-silicon and Eka-Boron respectivelyMendeleev also described some of the general physical properties of above elements.
⛤☛some Drawbacks of Mendeleev’s Periodic Table:- ⛤☛☺ Position of element hydrogen is not clear
⛤☛☺There is no place for isotopes of elements in his periodic table
-⛤☛☺ The placement of element having greater atomic mass before the elements having lower atomic mass could not be logically explained..⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤⛤☛☺☺☺☺☜⛤

Answer 2

Explanation:

• The Mendeleev's periodic law states that " The properties are a periodic function of their atomic mass." by using the atomic mass as the concept periodic classification of elements can be arranged in a groups.
