| Description | Match: |
How is an atom related to matter? | An atom is the smallest particles of matter. |
| What is the charge of a proton and what is the charge of a neutron? | A protons have a postitive charge and a neutron have a nuetral charge. |
| How do you know the number of protons in the nucleus of an atom? | the atomic number |
| Why is the atomic mass important? | Atomic Mass helps to determine how many neutrons are in an atom. |
| Describe why atoms are electrically nuetral. | Since there are the same number of protons and electrons in an atom, the charges cancel each other out. |
| What is an element? | An element is a prue substance that can't be broken down into simpler substances by ordinary chemical means. |
| How is an atom related to an element? | Each kind of atom is element |
| What is the particle located on the outside of the nucleus and what is it's charge? | An electron and it has a negative charge |
| List the particles located in the nucleus of an atom and their charge. | Protons, neutrons, electrons |
| What is the main feature used to distinguish the atoms of different kinds of elements? | the atomic structure |
| Define compound. | A substance produced when elements combine and whose properties are different from each of the elements. |
| What is the difference between a compound and a mixture? | Compound is formed chemically, while a mixture is when a pure substances combine but do not join. |
| What is the difference between a heterogeneous and homogenous mixture? | Both are combinations of pure substances, but homogeneous mixtures can easily be seperated by physical means. Homogeneous mixtures can not. |
| Compare and contrast compounds and mixtures? | Compounds and mixtures are both combinations of pure substances. Mixtures are joined but compounds do not. |
| What is the difference between an element and a compound? | A compound is formed chemically, while an element is formed physically. |
| Define matter. | Matter is the only thing that has a mass or volume. |
| Define mass. | Mass is the amount of matter in a substance |
| Define volume. | Volume is the amount of space the substance occupies |
| Define mixture. | A combination of compounds and elements that has not formed a new substance and whose proportions can be changed without changing the mixtures identity? |
| Define molecule. | A neutral particle formed when atoms share electrons. |
Sodium is an element found in table salt. It contains 11 protona and 12 neutrons. How many electrons are found in a neutral atom of sodium? |  Eleven |
