Ionic Compounds
| Question | Answer |
|---|---|
| mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together | chemical bond |
| results from the electrical attraction between cations and anions (positive and negative atoms) | ionic compounds |
| results from the sharing of electron pairs between two atoms | covalent bonds |
| results from the attraction between metal atoms and the surrounding sea of electrons | metallic bonds |
| an atom or group of bonded atoms that has a positive or negative charge | ion |
| lose electrons = _________ ion | positive |
| gain electrons = ________ ion | negative |
| number of electrons an element loses or gains | oxidation number |
| metals | losing |
| nonmetals | gaining |
| metals and positive ions are | first |
| nonmetals and negative ions are | second |
| ionic compounds are formed with a net charge of | zero |
| more than one element that is already bonded with an overall charge | polyatomic ions |
| _________ go around polyatomics that have more than one group | parenthesis |
