2.  a pure substance is a material in which all of the basic particles are identical.

3. the basic particles of an element are called atoms.

4. metals tend to be shiny solids and conduct heat and electric current well.

5. the three major categories of elements are metals, nonmetals and metalloids.]]> 2016-11-02 19:40:27 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134918701 336486 https://padlet.com/336486/6m1zl48xpv1t/wish/134921126 2016-11-02 19:48:51 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134921126 336486 https://padlet.com/336486/6m1zl48xpv1t/wish/134921320 2016-11-02 19:49:31 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134921320 336486 https://padlet.com/336486/6m1zl48xpv1t/wish/134921393 1. a compound is a pure substance composed of two or more elements that are chemically combined.

2. water is made of hydrogen and oxygen

3. the compound table salt is made of 2 elements, sodium and chlorine.

4. a compound can be identified by measuring or observing some of its properties.

5. each compound has characteristic properties.]]> 2016-11-02 19:49:51 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134921393 336486 https://padlet.com/336486/6m1zl48xpv1t/wish/134922750 2016-11-02 19:55:57 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134922750 336486 https://padlet.com/336486/6m1zl48xpv1t/wish/134924163 2016-11-02 20:01:34 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134924163 336486 https://padlet.com/336486/6m1zl48xpv1t/wish/134924234 1. making a mixture is therefore a physical change

2. because the components of a mixture are not changed into new chemicals, they can often be separated easily.

3. a solution is a homogeneous mixture.

4. the largest amount is called the solvent

5. the smaller amount are called solutes.]]> 2016-11-02 20:01:53 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134924234 336486 https://padlet.com/336486/6m1zl48xpv1t/wish/134925405 2016-11-02 20:06:40 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134925405 336486 https://padlet.com/336486/6m1zl48xpv1t/wish/134925434 2016-11-02 20:06:43 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134925434 336486 https://padlet.com/336486/6m1zl48xpv1t/wish/134925496 2016-11-02 20:06:48 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134925496 336486 https://padlet.com/336486/6m1zl48xpv1t/wish/134925571 2016-11-02 20:06:56 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134925571 336486 https://padlet.com/336486/6m1zl48xpv1t/wish/134925637 2016-11-02 20:07:10 UTC https://padlet.com/336486/6m1zl48xpv1t/wish/134925637
