What did the atom say to the cation?

Historical View of the Atom  Smallest piece of matter (Democritus, Greek philosopher)  Smallest particle of an element that can exist either alone or in combination (Webster’s dictionary)  Smallest particle which exhibits the characteristic chemical properties of an element.

Matter  An aggregate of material particles, capable of being located in space and time, and possesses the inherent property of inertia.  Elements, compounds, mixtures

Elements  A substance which cannot be divided into simpler substances. Is a hydrogen atom an element? Is a hydrogen molecule an element? 1 H 1.008

Compound  Pure substance consisting of elements, all bonded together in a similar fashion.  The composition is precisely defined. The ratio of elemental masses is always the same. Is water a compound? Is salt water a compound?

Mixtures  Matter consisting of more than one substance, with variable composition. Is salt water a mixture?

Properties of Matter  Intensive A quality of a pure substance which is independent of quantity color, melting point, hardness  Extensive A quality of a pure substance which is dependent on quantity mass, volume What are other intensive or extensive properties?

Properties of Matter Is density an intensive or extensive property? Are taste and smell intensive or extensive properties?
