- Forms of Chemical Bonds There are 3 forms bonding atoms:
Ioniccomplete transfer of 1 or more electrons from one atom to
another (one loses, the other gains) Covalentsome valence electrons
shared between atoms Metallic holds atoms of a metal together Most
bonds are somewhere in between ionic and covalent.

- NAMING COMPOUNDS Your ability to name compounds and write
formulas hinges on your ability to recognize whether a compound is
Ionic or Molecular.

- COMPOUNDS FORMED FROM IONS CATION + ANION ---> COMPOUND
COMPOUND CATION + ANION ---> COMPOUND COMPOUND Na + + Cl -
--> NaCl A neutral compound requires equal number of + equal
number of + and - charges. A neutral compound requires equal number
of + equal number of + and - charges.

- Naming Monatomic Ions Monatomic cations are identified simply
by the elements name. Examples: K + is called the potassium cation
Mg 2+ is called the magnesium cation
- Slide 7
- Naming Monatomic Ions For monatomic anions, the ending of the
elements name is dropped, and the ending ide is addend to the root
name. Examples: F - is called the fluoride anion N 3+ is called the
nitride anion
