Matter and Mixtures. Types of Matter Elements –Simplest of Substances –Made of only one type of atom –118 Known.

Composition of Matter Matter may be classified by its composition. Substances – matter that has a fixed composition. (pure) Matter can be an: ◦ Element.

UNIT 2 Classification of matter. An element is a pure substance that is made of one type of atom. Cannot be separated Anything on the Periodic table,

Classifying Matter. Matter: Anything that has mass and volume Organizing the Knowledge of Substances.

Matter anything with mass and volume Pure Substances can not be separated by physical means Mixtures can be separated by physical means Elements can not.

The Atom - Atoms react or not depending on its electron structure. - All atoms desire to have a full outer electron shell. - Metals will lose e - and nonmetals.

Element – a substance that cannot be broken down into simpler substance by chemical means. Atom – the smallest unit of an element that still has all of.

Differentiate between a mixture and a compound.. Key concepts/skills: Level 1: Define key vocabulary. Level 2: Given a substance, differentiate between.

Compounds and Mixtures. What is a compound?  Compound: pure substance made up of two or more elements chemically combined.  Compound is formed as a.

MATTER COMBINES TO FORM DIFFERENT SUBSTANCES. MATTER CAN BE PURE OR MIXED CAN BE PURE (made up of only one type of atom) CAN BE MIXED (made up of two.
