• The law of definite proportions states that the ratio of the masses of the two elements in a compound is always the same
• The law of multiple proportion states that when two elements form two different compounds, the masses would be a ratio of small whole numbers
• Isotopes are atoms of an element that have the same atomic #, but different atomic mass
• All matter is made up of atoms is apart of the Daltons Atomic Theory
• All atoms of an element are identical is apart of the daltons atomic theory.
• Atoms of different elements are different is apart of Daltons atomic theory
• Atoms consist of central nucleus and electrons is apart of Daltons Atomic Theory
• Diatomic means that they have two atoms
