What is a substance?

Substance is the solid, gaseous, liquid, or plasma form of matter having a definite chemical composition, properties, and structure. The different forms of substances are interchangeable in different states (solid, liquid, gas, plasma).

In this part of learning science, we can discuss different topics related to chemical substances formed by periodic table elements.
