Answer: substances that are made up of only one type of atom
Step-by-step explanation:
Element is a pure substance which is composed of atoms of similar elements. Example: Carbon (C)
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: water [tex]H_2O[/tex]
The subatomic particles with a positive charge are called as protons and are located in the nucleus of the atom.
Thus elements are substances that are made up of only one type of atom.
