(3) It's a lot easier to remember facts about 18 elements than over 100 elements.| Series: Usborne Illustrated Science Dictionaries (2) These eighteen elements make up most of the matter in the Universe. Remember that the orbitals are the places you will generally find the electrons as they spin around the nucleus. (1) Electrons fit nicely into three orbitals.

The rules for the first eighteen elements are very straightforward: You will never stop discovering new reactions and compounds, but the elements will be the same. With the tools you learn here, you can explore and understand the Universe. The iron atoms in the red soil of Mars are also the same. Iron (Fe) atoms found on Earth are identical to iron atoms found on meteorites. While there are more elements to discover, the basic elements remain the same. Scientists just confirmed the creation of element 117 in 2014. Up to this point in time, we have discovered or created about 120. Chemists have learned that over 95% of your body is made up of hydrogen (H), carbon (C), nitrogen, oxygen, phosphorus (P), and calcium (Ca).Īs far as we know, there are a limited number of basic elements. For example, you are made up of billions of billions of atoms but you probably won't find more than 40 elements (types of atoms) in your body. The term 'element' is used to describe atoms with specific characteristics. Remember that 'atom' is the general term. The atoms for each element are unique, even though they are all made of similar subatomic parts. If you have seven protons, neutrons, and electrons, you will have a nitrogen (N) atom. If you have eight protons, neutrons and electrons, you will have an oxygen (O) atom. When those pieces start combining in specific numbers, you can build atoms with recognizable traits. You know that a generic atom has some protons and neutrons in the nucleus and some electrons zipping around in orbitals.
