Chemistry Unit 2 - Finding Patterns
... The periodic table, arranged by atomic number, reveals a tendency for properties to repeat in a periodic pattern (periodicity), and can be used to predict the properties and uses of an element. These periodic trends exist for many properties of the elements including atomic radii, ionization energy, ...

ATOMS - Mr. Deets
... Law of Multiple Proportions – if two or more different compounds are composed of the same two elements, then the ratio of the masses of the second element combined with a certain mass of the first element is always a ratio of small whole numbers Example CO2 and CO : ratio of oxygen is always 2:1 ...
