Who gave three dimensional periodic table?
It was made by the Science Museum’s workshops in 1925, based on the periodic spiral of Alexandre de Chancourtois, a French geologist, who conceived it in 1862. The elements are plotted in order of atomic weight on a line that twists around a cylinder at an angle of 45 degrees.
What is the law of periodic table?
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.
