<h3>What are elements?</h3>

Elements are pure substances which are composed of similar atoms.

Elements are defined as substances which cannot be split into simpler substances by an ordinary chemical process.

Elements have different physical and chemical properties and can be classified into:

metals
semi-metals
non-metals

In conclusion, the physical and chemical properties of the elements vary from metals to non-metals.
