All existing matter in our surroundings is made up of basic units known as elements. Initially, in 1800, only 31 chemical elements were discovered. After some advancement in technology in 1865, about 63 more elements were discovered. This created the need for the periodic classification of elements.
Presently, there are 118 elements known to us. Out of these 118 chemical elements, some elements are man-made.
The periodic table, also known as the periodic table of the elements, is a rows and columns arrangement of the chemical elements. It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry.
Explanation:
Ha but agr use kuch bola na. I am sure me aake vha tumhe marungi. Crush hai mera uspe. Aur tum mere friend ho so itna to sun skte hona ek friend keliye.
