Chemistry Ionic Bond
Ionic Bonding Unit 2 Test
| Question | Answer |
|---|---|
| Why do elements chemically combine | To increase the stability of their electrons |
| Electrons are stable when they are in groups of? | Eight |
| Stability of eight groups is called? | Noble Gas Configuration |
| Valence electrons can do what between 2 elements? | Transfer and share |
| Chemical bonds hold how many atoms together? | Two |
| Ions form when? | Element gains or loses electrons |
| Ionic compounds form when? | Positive ions attract to negative ions |
| Elements in the same column of the periodic table have what in common? | Same valence electrons |
| Similar valence electrons cause elements in a group to? | React in similar ways |
| Lewis Dot Structure shows what about elements? | Valence electrons |
| Ionic Bonds form when? | Electrons are gained or lost by an element |
| Metals lose electrons to form? | Cations with a positive charge |
| Non-Metals gain electrons to form? | Anions with a negative charge |
| Opposite charges? | Attract to form the final ionic compound |
| If fewer than 4 electrons? | Electrons are lost, stable 8 energy level |
| More than 4 electrons? | Electrons are gained, stable 8 energy level |
| Formula Unit? | Smallest ratio of ions |
| Representative particle for ionic compounds? | Formula Unit |
| Chemical Formula? | Kinds and numbers of atoms in the smallest representative particle of the substance |
| Formation of Ionic compounds? | Always release energy |
| Reaction of ionic compound is? | Exothermic- release energy, feels hot |
| Lattice energy | Required to separate ions of an ionic compound |
| Many ionic compounds will? | Dissolve in water |
| Electron Sea Model? | Weakly held valence electrons move freely between atoms of metals |
| Metallic Bond? | Attraction of metallic cation for delocalized electrons |
