Chemistry Naming Compounds Flashcards

What is the process of naming molecular compounds?

1. name the elements

2. add the prefixes based on the # of each

3. make sure the 2nd elements ends in ide

ex. carbon dioxide

What numerical prefix is for 5

Penta

What number is the numerical prefix is for 6?

hexa

What number is the numerical prefix is for 7?

hepta

What number is the numerical prefix is for 8?

octa

What numerical prefix is for nine?

nona

What number is the numerical prefix is for 10?

deca

What is the process of naming ionic compounds in general?

1. Name the metal/cation first

2. State the element’s oxidation state as a Roman numeral in parentheses (for transition metals)

3. Name the non-metal with an -ide ending (or name the polyatomic anion)

ex. copper (I) chloride

ex. copper (II) chloride

IF i HAVE A POLYATOMIC ION IN A GENERAL COMPOUND IS THAT COMPOUND MOLECULAR OR IONIC?

Ionic

When it comes to identifying similar polyatomic  ions, what is unique about the number of oxygen atoms in each type?

More oxygen ending - ate

Less oxygen ending - ite

ex. Sulfate (SO4) 2-

ex. Sulfite (S03) 2-

What is the name of this polyatmic ion : (SO3)2-

sulfite

What is the name of this polyatomic ion: (SO4)2-

Sulfate
