Transition Metal Cations Transition metals have variable charges; they can lose different numbers of electrons. All transition metals, tin and lead –E–Except not Ag +, Cd +2, Zn +2 Rule for naming: –N–Name the metal –T–Tell the charge using Roman Numerals –A–Add the word “ion”

Roman Numerals 1, I 2, II 3, III 4, IV 5, V 6, VI 7, VII 8, VIII 9, IX 10, X

Binary Ionic Date:

Binary Ionic What 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 1 Balance 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.

NaCl BaF LiS AlO

Method 2 Lowest 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.

KBr MgI HO GaS

Method 3 Crossover 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.

KS SrP AlF CaO

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”
