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 |
