Elements can be classified in a number of ways:
Elements can be classified based on their atomic number, which determines the number of protons in the nucleus. This leads to elements being organized in the Periodic Table based on increasing atomic number. Elements can also be classified into groups or families based on similar chemical properties, such as the noble gases or alkali metals.
