Presentation on theme: "Does the compound contain a metal or a polyatomic ion? NO. Is the first element in the compound hydrogen? YES Is the first element in the compound hydrogen?"— Presentation transcript:

1 Does the compound contain a metal or a polyatomic ion? NO. Is the first element in the compound hydrogen? YES Is the first element in the compound hydrogen? NO. This is an ionic compound. Name the positive ion. Is the positive ion a metal? YES. Is it a metal with only one possible charge? Name the metal. NO. Name the metal followed by a Roman Numeral equal to its charge. Name the negative ion. Is the negative ion a nonmetal? YES. Name the nonmetal by changing its ending to –ide. NO. It’s a polyatomic ion. Name the polyatomic ion. NO. This is a molecular (covalent) compound. YES. Put the appropriate prefix in front of the element name. NO. Is the subscript on the first element in the compound 2 or greater? NO. Name the element. Name the second element by putting the appropriate prefix in front of the element name and changing the ending to –ide. NO. It’s a polyatomic ion. Name the polyatomic ion. YES. The compound is an acid. Go to the “naming acids flowchart” Naming compounds flowchart Is the ionic compound followed by #H 2 O? NO. you are finished! YES. Your compound is a hydrate. Follow with the appropriate prefix to represent the coefficient in front of the H 2 O and the word “hydrate.” Does the compound contain both carbon and hydrogen? YES. The compound is organic. Go to the “naming organic compounds flowchart”

2 Does the acid contain more than 2 different elements? NO. It is a binary acid. Start the acid name with the prefix hydro- Followed by the root name of the nonmetal Ending with the suffix –ic acid. YES. It is a ternary acid containing a polyatomic ion. Does the name of the polyatomic ion end in –ate? YES. Change the ending of the polyatomic ion to –ic and add the word acid. NO. The polyatomic ion must end in –ite. Change the ending to –ous and add the word acid. NAMING ACIDS FLOWCHART
