elements are the common unit of atoms. each unique element is defined by the number of protons an atom has. if an atom has one proton, it is hydrogen, two is helium, and so on.
here is a website with a list of all the elements

A chemical element, or an element, is a material which cannot be broken down or changed into another substance using chemical means. Elements may be thought of as the basic chemical building blocks of matter. Depending on how much evidence you require to prove a new element has been created, there are 117 or 118 known elements

An element is a substance that is unique that no element is the same as another. There may exist similar properties but most of its properties is unique to itself as proved by the study of material scientist. This is said to because of its atomic number or the number of atoms present in the element.

Elements are the basic building blocks. They are the purest thing. Each element is made up of different number of Protons(+ve particles) Neutrons(neutral particles). These Neutrons and Protons make the nucleas. Then we have something called Electrons(-ve particles) which revolve around the nucleas in paths according to their energies.
