So far, scientists have found out 118 chemical elements. All these elements are listed and arranged in the periodic table of elements. Out of these known elements, only 98 are naturally occurring; the rest are synthesized. Thus, we can say that 98 elements are there on Earth. The heavier elements are synthesized in controlled conditions by combining smaller elements, using a particle accelerator. Many of the heavier elements are very unstable and are also radioactive. 

The elements can be divided into metals, non-metals and metalloids. Most of the known elements are metals. Many of these known elements are present in pure forms, while others are found in combined forms, on Earth. 

Elements consist of atoms, which are formed by protons, neutrons and electrons. While the protons and neutrons constitute the nucleus, electrons are located outside of it.
