What is the difference between compound and atom?
An atom is the basic building block of an element. It is the smallest particle in an Element and a compound. They are highly reactive in nature. Atoms do not exist in the free state. (Exception -Noble gases).
A compound is a substance made up of two or more elements chemically bonded together. Compounds are represented by their chemical formula. For example table salt is represented as NaCl.
Explanation:
The chemical formula of water is H2O, thus water is made of two hydrogen atoms and one oxygen atom. The atoms in a compound possess strong chemical bonds and hence cannot be separated easily.
All the matter in the universe is made of tiny particles known as atoms. In nature, 92 different kinds of atoms are present. These atoms combine with one another to form different kinds of matter. For example, Gold is made up of only gold atoms. When the matter is made of only one kind of atom, it is called an element.
