2. Ion Formation Using the Periodic Table
Cations: Names of cations do not change from neutral atom, just add the word “ion” to the end of the element.
(**Use your colored periodic table!!**)
What is the charge of the following ions?
sodium ion
_______
beryllium ion _______
aluminum ion _____
silver ion ______
Transition Metals: The charge of the ion is given by the roman numeral. These are cations so names follow
the same rule as above!
I-1
VI - 6
II - 2
VII - 7
III - 3
VIII - 8
IV - 4
IX - 9
V-5
X – 10
What is the charge of the following ions?
copper (I) ion _____
cobalt (II) ion ______
tin(IV) ion ______
iron(III) ion _______
Anions: Names of ions change by adding the suffix “ide” to the element name
(**Add -2 above the Oxygen family and -3 above the Nitrogen Family on your colored Periodic Table**)
