1
New cards

State the naming conventions for binary ionic compounds

  • Name of cation comes first and the anion second

  • The name of the cation is the same as the metal

  • add the suffix “-ide” to the root of the nonmetal

2
New cards

State the common name of the Cr cations

  • Cr²+ = Chromous

  • Cr³+ = Chromic

3
New cards

State the name of the Cu cations

  • Cu²+ = Cuprous

  • Cu³+ = Cupric

4
New cards

State the common names of the Fe cations

  • Fe²+ = Ferrous

  • Fe³+ = Ferric

5
New cards

State the common names of the Hg cations

  • Hg²+ = Mercurous

  • Hg³+ = Mercuric

6
New cards

State the common names of the Sn cations

  • Sn²+ = Stannous

  • Sn4+ = Stannic

7
New cards

State the naming conventions for ionic compounds with polyatomic ions

  • Same as for monoatomic ions but the suffix of the polyatomic ion is different

8
New cards

State the naming conventions for binary acids

  • hydro- + anion nonmetal root + -ic + acid

9
New cards

State the naming conventions for oxoacids

  • Anion’s “-ate” changes to “-ic”

  • Anion’s “-ite” changes to “-ous”

10
New cards

State the naming conventions of binary covalent compounds

  • Lower group number element goes first

  • Second element is added with the “-ide” root

  • Numerical prefixes are added to both elements to indicate their number of atoms
