The elements are the building blocks of everything in the universe. You will realize that these elements make up the planets of our solar system, the air we breathe, the ground we walk on, our bodies and so on. There are more than 100 different elements. The sand that you step on is made of the elements silicon (Si) and oxygen (O).The air you breathe is mostly oxygen (O) and nitrogen(N).
In addition, there are other gases such as argon (Ar),Krypton (Kr),hydrogen (H),carbon (C),helium (He) and so on. Salt is made of elements Sodium (Na) and chlorine (Cl).Gold is an element that is used to make earrings, necklaces and other pieces of jewelry worn by people.

However, those are some of the elements that have been on the periodic table from the onset. You can readily find a periodic table in a Chemistry laboratory or class .This periodic table is used to guide students when it comes to elements and their atomic numbers. Did you know that there are some elements that have been added to the periodic table? Elements whose atomic numbers are 113,115,117 and 118 have been added to the periodic table. They are the newest elements on the periodic table. These new elements were actually added after indepth research was done and fulfilled the required needed criteria.
These new elements are ununtrium, ununpentium, ununseptium and ununoctium respectively. You can readily find these elements in the periodic table. Scientists have continued to do their own research on the various elements that exist so far.Scientists have discovered that these elements have tiny individual particles which are called atoms. If elements are made out of atoms, then what makes up an atom? In early 20th century, scientists discovered that atoms are made of three smaller particles namely: electrons, protons and neutrons.
Those are the newest elements on the periodic table. You can readily find them on the periodic table.
