How many elements are there on the world?

Elements:
The same type of atoms, physical or chemical means is indistinguishable from selfsimpler substances and purest of different substances is called an element.
The distance between the atoms and atoms of an element are formed are of the same size. However, with another element atoms are atoms of an element size and the distances between the different atoms. The same elements are composed of atoms of different substances in the same kind.

The distance of each element of the element atoms in the solid state, liquid and gas varies. All elements are composed of animate and inanimate.
There are 118 elements known today. Although one of these 92 elements in nature,synthetic elements from the rest of the laboratories.
The elements are represented by symbols and the symbol of each element are unique.

Element Properties:

1 - The smallest structural unit is the atom.
2 - composed of the same kind of atoms.
3 - Self-simpler and more different materials are separated.
4 - Pure Substances.
5 –Elements  are shown with symbols.
