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 |
