The Periodic Table of the Elements is a way of classifying the known atoms in this Universe. Each element contains only one kind of atom and loses individual characteristics when broken down into subatomic particles. However, radioactive elements can contain various charges.
Hydrogen (H) is said to have been the first element formed by the explosion of the Sun, and other elements may have been formed from it. H is the most common element.
Helium is the second element on the table, and was discovered on the Moon before it was discovered on Earth.
Many elements are essential to life and even more are necessary for health. Some are toxic in our bodies, such as lead and aluminum.
