Topic: Classifying Matter E.Q.: What are the different ways you could classify matter?

What is matter?  Matter is anything that has mass and takes up space.

What is matter made of?  Atoms- the most basic unit of matter. All matter is made up of atoms.  Elements- The building blocks of matter that can only be made up of one type of atom.

How are elements represented?  Elements are represented by chemical symbols. Chemical symbols are just shorted versions of the elements names. Chemical symbols are just shorted versions of the elements names.  All elements are found on the Periodic Table of Elements.

What is the difference between elements and compounds?  Elements are made up of only ONE type of atom.  Compounds are made up of TWO or MORE types of atoms.

What are the ways you can tell the difference?  Elements? Have a square on the Periodic Table Have a square on the Periodic Table Only have ONE capital letter Only have ONE capital letter  Compounds? The WHOLE compound cannot be found on the Periodic Table Has MORE THAN ONE capital letter and/or has a number. ClO 3 CaCO 3 H2O2H2O2H2O2H2O2

What is a mixture?  Two or more substances that are combined but keep their own properties. Examples Examples

How else could we classify matter?  We can classify matter by its physical properties.  Physical properties include: Malleability Malleability Insulator Insulator Conductor Conductor Brittle Brittle Luster Luster

What is malleability?  Matter being capable of being pounded or rolled into thin sheets without shattering.

What is brittle?  Matter being l ikely to shatter or break into pieces when pounded.

What is a conductor?  Matter that allows electricity or heat to flow through it easily.

What is an insulator?  Matter that does not allow electricity or heat to pass through easily

What is shiny luster?  Matter that reflects light.

What is dull luster?  Matter that does not reflect light.

What is one last way to classify matter?  One last way to classify matter is by determining whether it is a metal, nonmetal or metalloid. Metal- Most elements are metals; They usually have shiny luster, are malleable and a good conductor of both electricity and heat. Metal- Most elements are metals; They usually have shiny luster, are malleable and a good conductor of both electricity and heat.

What is one last way to classify matter? Nonmetals- Located on the right side of the Periodic Table; has dull luster, brittle and a good insulator of both heat and electricity. Nonmetals- Located on the right side of the Periodic Table; has dull luster, brittle and a good insulator of both heat and electricity. Metalloids- Elements that have properties of both metals and nonmetals. They can have either shiny or dull luster. They can either be an insulator or a conductor. Metalloids- Elements that have properties of both metals and nonmetals. They can have either shiny or dull luster. They can either be an insulator or a conductor.
