1) 2) Main group metals tend to form cations with charges equal to their group numbers eg Na* (Na is in group IA), Mg²+ (Magnesium is in group IIIA) and AB+ (Aluminum is in group IIIA) form cations and form anions. 3) Nonmetals tend to form anions with charges equal to their group number minus 8. eg F (F is in grp VIIA, 7-8 =-1), O²- (Oxygen is in grp VIA, 6-8=-2) and N3- (Nitrogen is in grp VA, 5-8=-3) 4) TypeI metals have invariant charge (it never changes). Examples of Type I metals include 5) Type II metals can have multiple charges. Examples of Type II metals include Model 1 - Ion Charges for Selected Elements 1. 2 Be2 -EN 3. Na* Mg Transition elements Fe2+ Fe3r Ca Ni2 Cu Ga3+ Zn2 Br'- 4. Cu Rb Sr. Cd2+ Sn2 Il- Pb2 Pb4+ Ba2. 9. Cations- -Anions 1. Based on the information in Model 1: a. What is the charge on the ions formed from alkali metals? b. What is the charge on the ions formed from the alkaline earth metals? c. What is the charge on the ions formed by the halogens? d. Identify three elements that can only form one cation? e. Identify three elements that can only form one anion. f. Identify three elements that can form more than one cation. g. Is there a particular region of the periodic table where these "multiple ion" elements are usually located in? h. Are there any elements from this particular region of the periodic table that do not form more than one ion (or form only an ion with a single charge).
