Periodic Table of Elements

The periodic table is said to be the most important part of chemistry as it makes it. All the elements are arranged in an informative order. They are positioned in the order from left to right and also top to bottom in increasing order of their atomic numbers. This order coincides with the increase in their atomic mass.

Every chemical element consists of a particular atomic number illustrating a number of protons present within the nucleus. Most of the elements are isotopes. They are grouped under a single element, and they are never separated in the table.
