What is a pure substance? Is a substance in which there is a uniform composition of “particles”. The particles we are talking about are atoms.
What is an element? meet the elements song A substance that Contains only one type of atom. All known elements are organized on the periodic table of elements. atoms and elements
What is a compound? Is a combination of elements that come together through a chemical reaction and becomes something called a molecule. • A molecule is two or more different elements combined in a specific ratio.

How do Atoms of Different Elements Differ? • Starting Simply The hydrogen atom has one proton and one electron. • Now for Some Neutrons The helium atom has two protons, two neutrons, and two electrons. • Building Bigger Atoms For bigger atoms, simply add protons, neutrons, and electrons. • Protons and Atomic Number . The atomic number represents the number of protons in the nucleus of the atom.
