Elements

• If the formula has ONE CAPITAL LETTER, it is an
  element, and its name is what is found on the
  periodic table (regardless of subscript)

3
IONS

• Positive ions are named for the element
• Na is the sodium ion
• Negative ions end in -ide
• Cl- is the chloride ion
• Check table E for polyatomic ions (like NO3-)

4

• all TWO element compounds (two capital letters)
  end in IDE, whether molecular or ionic
• NF3 nitrogen trifluoride
• CaCl2 calcium chloride

5

• MOLECULAR COMPOUNDS
• - start with a NON-METAL
• - use PREFIXES in the name
• P2O5
• diphosphorus pentoxide

6

• IONIC COMPOUNDS
