Hope this helps.eport Abuse. an atom is the smallest undevidable substance of matter. an element is a substance made by two similar atome by a covalent bond. a molecule is a group of atoms; different ,made by a covalent bond. a compound is a substance made by ionic bond.
An element is a substance made from only one type of atom. Remember this definition as you might need it in the exam! For example Carbon is made entirely from carbon atoms. Sodium is made entirely from sodium atoms. Unlike a compound, an element cannot be broken down (chemically) into a more simple substance. The periodic table shows all the elements. Atoms of the same element have the same number of protons and therefore have the same atomic number.
