Classifying Matter: Elements, Compounds, and Mixtures

All matter has certain characteristics in common that separate it from whatever is not

All matter has certain characteristics in common that separate it from whatever is not matter. Can you tell which is which? Work with a partner at your table. You will be given a set of cards. Each card has 6 items on it. Try and classify all the items in the chart. What characteristics does the matter have that the not matter does not?

Does it Matter or NOT Matter Not Matter

Does it Matter or NOT Matter Not Matter

What is Matter is anything that has mass and takes up space Matter is made up of atoms. An atom is the smallest unit of matter Atoms can combine or bond to form a molecule

Pure Substances A sample of matter that has definite chemical and physical properties.

Pure Substances A sample of matter that has definite chemical and physical properties.

Elements pure substance that cannot be separated into simpler substance by physical or chemical

Elements pure substance that cannot be separated into simpler substance by physical or chemical means.

Compounds Pure substance composed of two or more different elements joined by chemical bonds.

Compounds Pure substance composed of two or more different elements joined by chemical bonds. Made of elements in a specific ratio that is always the same Has a chemical formula Can only be separated by chemical means, not physically

Mixtures A combination of two or more pure substances that are not chemically combined.

Mixtures A combination of two or more pure substances that are not chemically combined. substances held together by physical forces, not chemical No chemical change takes place Each item retains its properties in the mixture They can be separated physically Chem 4 kids. com

Can you identify the following? You will be shown a series of photos. Tell if each photo represents an item composed of an element, compound, or mixture. Review: An element contains just one type of atom. A compound contains two or more different atoms joined together. A mixture contains two or more different substances that are only physically joined together, not chemically. A mixture can contain both elements and compounds.

Types of Mixtures Two main categories Homogeneous – molecules are mixed up in an even distribution Heterogeneous – molecules are not mixed up in an even distribution

Homogeneous Mixtures Solutions- a well mixed mixture— appears to be a single substance Solute

Homogeneous Mixtures Solutions- a well mixed mixture— appears to be a single substance Solute - the substance being dissolved Solvent – the substance in which the solute is being dissolved water is considered a universal solvent Particles do not scatter light

Homogeneous Mixtures Colloids- a mixture of tiny particles that are bigger than those in

Homogeneous Mixtures Colloids- a mixture of tiny particles that are bigger than those in a solution, but smaller than in a suspension Do not settle out over time Scatter light Ex. Mayonnaise, milk, gelatin, whipped cream

Heterogeneous Mixtures Suspensions – a mixture in which particles are dispersed in liquid or

Heterogeneous Mixtures Suspensions – a mixture in which particles are dispersed in liquid or a gas and will eventually settle out Particles can scatter light Can be filtered out using a filter Ex. Snow globe, sand in a bucket of water, muddy water, Italian salad dressing
