Transition Metal Cations

• Transition metals have variable charges; they can lose different numbers of electrons.

• All transition metals, tin and lead– Except not Ag+, Cd+2, Zn+2

• Rule for naming:– Name the metal– Tell the charge using Roman Numerals– Add the word “ion”

Roman Numerals

Binary IonicDate:

Binary IonicWhat is that?

• Binary = 2• Ionic = ions!

– One Cation (metal in blue) and one Anion (nonmetal in red)

– No metalloids (purple)

Creating Compounds

• Need to balance the number of electrons transferred between the cation and anion.

• There are three methods for creating compounds. I will make you an expert at each!

Method 1Balance e- transferred

• Draw each atom with valence electrons around it as dots.

• Draw a line to show the electron moving from the metal to the nonmetal.

• Continue transferring electrons until each atom has it’s noble gas configuration.– It may be necessary to add more atoms.

• Na Cl

• Ba F

• Li S

• Al O

Method 2Lowest Common Multiple

• Look at the oxidation numbers (charges) for the cation and anion.

• Determine the lowest common multiple of the charges.

• Determine how many cations and anions are necessary so that the charges add up to zero.

• K Br

• Mg I

• H O

• Ga S

Method 3Crossover

• Take the charge of the cation, drop the + and write it as the subscript of the anion.

• Take the charge of the anion, drop the – and write it as the subscript of the cation.

• K S

• Sr P

• Al F

• Ca O

Naming Binary Ionic

• Name the metal– If transition metal, Sn or Pb, tell the charge in ( ).– If Zn, Cd or Ag, just name.

• Name the nonmetal with “-ide”
