Multiple Choice

• $$C_6H_{12}O_6$$  

• $$H_2O$$  

• $$Ca_2O_2$$  

• $$C_4H_{12}$$  

Naming Type 1 Compounds

NaCl --> sodium chloride

​

​KI --> potassium iodide

​

​BaO --> barium oxide

Multiple Choice

Which of the following is NOT a type 1 compound?

• KBr

• AgBr

• SrBr₂

• AlBr₃

​Practice Naming Type 2 Compounds

​Ni2O --> nickel (I) oxide

​ we name this nickel (I) rather than nickel alone because as a transition metal, nickel can form more than one different ion when it bonds

​

​NbCl5 --> niobium (V) chloride

​ again, as a transition metal we name this niobium (V) because this is the ion that bonded with Cl-1 to form the compound

​We can use the ions to write the chemical formula of a type (II) compound)

​iron (III) fluoride is the bond between Fe+3 and F-1 meaning that the compound formed is:

​

​FeF3

​This means....

​1. Compounds with Zn, Cd, and Ag are not named with roman numerals even though they are transition metals.

​

​2. Compounds with Sn and Pb are named with roman numerals even though they are not transition metals.

​Therefore,

​AgF --> silver fluoride

​

​PbS --> lead (II) sulfide
