Is it a compound? FIRST OF ALL… YESNO

INVALID CHOICE You have to go back lol

Metals and Nonmetals and/or Polyatomic Ions? 2 or more nonmetals? DOES IT HAVE… Polyatomic Ion Sheet Periodic Table Then its IONIC! Then its COVALENT!

IS IT… Has 2 elements Has a water molecule IONIC Polyatomic? Hydrated Crystal? Binary? Polyatomic Ion Sheet Back to Main

CATION (Positively Charged Polyatomic Ion) Naming Rules:  Polyatomic ion comes first  Negatively charged element follows ANION (Negatively Charged Polyatomic Ion) Naming Rules:  Positively charged element comes first  Polyatomic ion follows POLYATOMIC FINAL RESULT! Back to Ionic

Element/Polyatomic Ion with H 2 O molecule H 2 O molecule with a prefix  If there is a number in front of your water molecule, see Prefix Chart HYDRATED CRYSTAL FINAL RESULT! Prefix Chart Back to Ionic

First Element Name  Simply name the element used first! Second Element Name  Chop off the ending and add –ide! BINARY FINAL RESULT! Criss Cross Method Naming Rules Back to Ionic

The compound needs to be stable! When you put the ions together, the overall charge still needs to equal zero. You write the cation (positve ion) first, including its charge. Next, you write the anion (negative ion) including its charge. You “criss cross” the charges to form subscripts on the opposite ions! CRISS CROSS METHOD GO BACK

You need to write the cation first (Refer to Periodic Table for its name). If the cation is a metal that contains multiple charges, you have to specify the charge. You do this by writing the number as a Roman Numeral in parenthesis after the cation. Next, write the anion (Refer to Periodic Table for its name). Drop the ending, and add the sufix –ide. If there is a polyatomic ion present, refer to polyatomic ion sheet for its name. NAMING RULES FOR IONIC BONDS Periodic Table

First Element Name  See naming rules  Use appropriate element name and prefix. Second Element Name  See naming rules  Use appropriate element name and prefix.  Don’t forget- chop off ending and add –ide! COVALENT Naming Rules Final Results! Back to Main

First, the cation (positive ion) should be named. Do not cut off any parts of the element’s name.  If there is a subscript of 2 or more, see Prefix Chart Next, the anion (negative ion) should be named.  If the element begins with a vowel, the (a) and (o) are dropped from the end of the prefix  If there is a subscript of 2 or more, see Prefix Chart NAMING RULES FOR COVALENT BONDS Prefix Chart

Place prefix in front of the hydrate (water molecule) PREFIX CHART GO BACK

For the cation, just place the appropriate prefix (DO NOT use mono- even if there is a subscript of 1) For the anion, place the appropriate prefix in front of the element name. PREFIX CHART GO BACK

Any element to the left of the stepline (including those immediately along it) are METALS Any element to the right of stepline (not immediately on it) are NONMETALS METAL OR NONMETAL? GO BACK
