concept of element

In general knowledge, an element is a fundamental substance that cannot be broken down into simpler substances by chemical means. Each element is defined by its unique number of protons, which determines its properties and place in the periodic table. Elements combine in various ways to form compounds, creating everything from the air we breathe to the materials we use daily. Examples of elements include hydrogen, oxygen, and carbon. Understanding elements is essential to grasping the basics of chemistry and the composition of matter in our world.
