Example:
Elements: Some of the most basic chemical compounds those cannot be altered by a chemical reaction or any other chemical process. Elements are composed of atoms with the same number of protons.
 
The simplest form of matter is an element. In our everyday lives, we use a variety of components.
  • Water is made up of two elements: Hydrogen and oxygen.
  • Magnesium and Phosphorus are used in the production of crackers.
  • In agriculture, sulphur is used as a fertiliser.
  • The elements sodium and chlorine are found in common salt.
  • Mobile phones are made of gallium, while computer chips are made of silicon.
Note: Till date, \(118\) elements have been identified. \(94\) of these elements are found in nature, while \(24\) have been produced artificially in the lab.
Classification of Elements:
Elements are the fundamental substances that cannot be separated into simpler substances by any chemical methods.

According to Antoine Laurent Lavoisier, an element is a fundamental type of matter that cannot be broken down into simpler substance by chemical reactions.
Based on their chemical properties, we divide the elements into Metals, Non-metals, and Metalloids.
  
Let us discuss about metals, non-metals and metalloids in upcoming section.
