What is the main idea in the periodic law?
Here, we are going to discuss the main idea in the periodic law.
Periodic law states that when the elements are arranged in the increasing order of atomic numbers, their physical and chemical properties repeat. The main idea is to arrange the elements in the periodic table.
The atomic number gives us the number of protons in the nucleus of an atom and this number increases by one in going from one element to the next. Elements, when arranged in order of increasing atomic number Z, lead us to the classification known as the Modern Periodic Table.
