Three basic types of bonds | Ionic, covalent, metallic |
Ionic Bonds def | Electrostatic attraction b/t ions |
Covalent bonds def | share electrons |
Metallic bonds | metal atoms bonded to several other atoms |
Lattice energy def | "strength of the bond" the energy required to separate a mole of an ionic compound into its gaseous ions |
Lattice energy _____ with the decrease in size of ions | increases |
Lattice energy ______ with the charge on the ions | increases |
The ________ of the ions helps differentiate/compare lattice energy | Size of the ions |
Covalent Bonding electrostatic interaction | attractions b/t e-'s, repulsions b/t e-'s, repulsions b/t nuclei |
polar covalent bonds def | unequally shared e-'s ie: HF |
pure covalent bonds def | equally shared e-'s ie: F2 |
