elements are all, at their smallest, individual atoms. Any individual atom will have the same number of protons and most of the time the same number of electrons. Certain elements can have varying numbers of neutrons which can affect their atomic weight and make them different from other atoms of the same type. These are called Isotopes.

It is mainly because of the electrostatic attraction between the positively charged nucleus and negatively charged electrons going around the nuclei of the atoms. So they form covalent or ionic or coordinate bonds among the elementary atoms. Hence molecules are formed.

What other elements are in a compound?

A compound consists of a mixture of two or more molecules. Molecules are composed of elements or atoms bonded together in a specific way. Hope this helps!


Are elements composed of compounds?

No, an element is made up of atoms of a certain atomic number. A compound is a group of molecules consisting of atoms from many different elements that make up a new substance. A compound such as NaCl is made up of sodium chloride molecules. Each NaCl molecule has a sodium and chlorine atom in it.
