Element
An element is Chemical material in its simplest form, such as hydrogen, helium, oxygen, carbon, etc. An element can be a solid, a liquid or a gas. Matter is made up of many elements. There are 105 elements in total.
The Solar System was formed out of a cloud of matter. The elements in this matter combined with other elements as they formed the Sun and planets. For example, when carbon combined with oxygen, it formed carbon dioxide.
