6.MA2Trends&Bonds
chemical bonds, ions trends
| Term | Definition |
|---|---|
| trend | pattern that continues and can be predicted due to properties and characteristics |
| chemical bond | force that allow atoms or ions are bound in a molecule |
| ionic bond | chemical bond between metals and nonmetals that TRANSFER electrons |
| covalent bond | chemcial bond between 2 nonmetals that SHARE electrons |
| oxidation number | a number assigned to an element in certain families that represents the number of electrons lost (or gained, if the number is negative) by an atom of that element in order to become stable with a full outer electron shell |
| ion | charged atom |
| anion | negatively charged atom (ion) that has gained electrons |
| cation | postively charged atom (ion) that has lost electrons |
| charged | being either + or - with an imbalance of electrons and protons |
| neutral | no charge; equal number of electrons and protons |
| noble gases | group 18 of the periodic table, full electron shells; stable elements |
| inert | do not react; noble gases are inert |
| stable | balanced atom or element that is not reactive, and does not need to do anything or bond to be balanced and equal in all ways; inert |
| atomic radius | distance from the nucleus of an atom to the outside edge of the electron cloud; describes the size of an atom |
