When people talk about elements, they’re usually talking about chemical elements. These special chemicals are the ingredients for every thing that exists. Whether something is living, like a person, or not living, like a rock, it’s made of elements. Some common elements that you might have heard of are oxygen, gold, silver, carbon, helium, and neon.
So far, 117 elements have been found. We know that 94 of them occur naturally and the rest have been made in science laboratories.
Everything in the room you are in right now is made up of elements in different combinations even the air! Air is mostly made up of an element called nitrogen, but there is also oxygen, carbon, and a little bit of some other elements like argon. People are made up of elements too! We’re mostly carbon, hydrogen, oxygen and nitrogen!
