The Periodic Table of Elements

An element if the simplest form of matter in that it cannot be further broken down using any chemical methods. To understand this well, it is important to know the regularity between them by classifying them scientifically and dividing elements with similar property into several groups. To classify elements, they are arranged in order of atomic number, and similar elements are arranged in the same line with a regular interval. Among types of registered elements, elements from 1~92 were discovered in nature, and those from 93 were artificially synthesized.
