| Question | Answer |
|---|---|
| matter | anything that takes up space and hass mass |
| mass | the material that matter is made up of. |
| space | how much room value matter takes up |
| density | the amount of materiel matter takes up within a specific space |
| atom | smallest part of an element and makes them all up |
| electron | negative charge, moves all around and are attracted to each other |
| proton | particles of an atom with a positive charge located inside the nucleus |
| neutron | particle of an atom with no charge inside the nucleus with a proton |
| periodic table | large grid that has all the elements and classifies them |
| element | can not be broken down and they make up everything in the universe |
| rows | tells how many energy levels each element has |
| columns | columns tell how many valence electrons each element has, the number of electrons, and energy level |
| valence electrons | the electrons that move on the outer shell |
| atomic number | how many protons an element has inside the nucleus |
| atomic mass | the measurement of the mass for an elements atoms |
| chemical property | to combine and make a whole new substance |
| physical property | the state of matter and appearance of a substance |
| ionic bond | when elements lose or gain a electron during bonding |
| covalent bond | when elements share electrons during bonding |
| reaction | elements bond with electrons to make a change or reaction |
| compound | two or more elements combine to create a whole new substance |
| mixture | two or more substances combine but stay the same |
| Nobel gases | elements with 8 electrons and are in group 18 |
| halogens | bond easily with elements and have 7 valence electrons |
| alkali metals | very reactive because they only have 1 valence electron |
| metalloids | elements between metals and non metals that can react either way and they have 3 - 7 valence electrons |
