Atom :-

❍ Firstly, atoms are the basic building blocks of all matter on Earth and they're very tiny (far too small to be seen with the naked eye). Substances can be categorised as either elements or compounds. Both of these are made up of atoms, the only difference is an element is made of one type of atom whereas compounds are made of two or more different types of atoms.

❍ Example of an Atom are Neon (Ne) Hydrogen (H) Argon (Ar) Iron (Fe) Calcium (Ca)Deuterium

Element :-

❍ A substance that cannot be broken down into simpler substances by chemical means. An element is composed of atoms that have the same atomic number, that is, each atom has the same number of protons in its nucleus as all other atoms of that element.

Example of elements are iron, copper, silver, gold, hydrogen, carbon, nitrogen, and oxygen.

Compound :-

❍ When two or more elements chemically combine in a fixed ratio by mass, the obtained product is known as a compound. Compounds can be defined as substances consisting of 2 or more different types of elements in a fixed ratio of its atoms.

❍ Example of compound are Water, carbon dioxide and table salt.
