Matters Smallest Particles Matter Is Made Up Of Elements

Nanotechnology's raw materials are the chemical elements. Any sample of matter, whether it is a gas, liquid, or solid, is either an element or is composed of several elements. Elements are known as the building blocks of matter. An element consists purely of atoms of one kind. It is a substance composed of pure chemicals that cannot be separated into simpler substances. Therefore, an element is always an element, even at the nanoscale.

Sulfur, copper, carbon, oxygen, iron are some common examples of pure chemical elements. Just four of these—carbon (C), oxygen (O), hydrogen (H), and nitrogen (N)—make up approximately 96 percent of the human body. Much of Earth, including the universe, consists of several elements, such as carbon, hydrogen, oxygen, and nitrogen that are found in our bodies, too. Other common elements include iron, copper, calcium, nickel, potassium, and mercury. Many of these elements are listed on the side of vitamin bottles.
