| Definition of Proton | Positively charged particle found in nucleus
🗑
|

| Definition of Electron | Negatively charged particle that orbits nucleus
🗑
|
||||
| Definition of Neutron | a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
A particle found in the nucleus has a neutral charge

| Definition of a Mixture | Easy to separate, created through physical change, retains the properties of substances it is made of - Trail Mix, raisins.
Made up of elements, compounds or both
🗑
|

| Definition of Compound | Hard to separate, created by chemical change, does not retain the properties of the substance that make it up - example:salt. Made up of just elements.
🗑
|

| Examples of Compound | A pure substance that is made up of 2 or more elements joined together that are chemically bonded. Examples: Table salt, water, vinegar, baking soda, carbon dioxide
🗑
|
||||
| Examples of Chemical Change | A reaction between 2 or more substances that produces one or more new substances with different properties.Examples of chemical properties are: heat of combustion, reactivity with water, PH, and electromotive force.
🗑
|
||||
| Examples of Physical Change | Matter does not change the matter into another kind of matter.Examples
are: color, smell, freezing point, boiling point, melting point, and density. Note that measuring each of these properties will not alter the basic nature of the substance.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
