akcapr Posted May 14, 2005 Share Posted May 14, 2005 this is sort of a simple question, but how do you figure out the charge an ion will have when it is dissolved and what the ion itself will be? Ive always known alot of ions just by memory so i dint really need to know, but if i dont know one, can i use the periodic table to figure it out or something of that sort?

Crash Posted May 14, 2005 Share Posted May 14, 2005 Yea sorta, remember to form ions an atom will try to get its outer octet closer to the nearest noble gass electronic structure, bt you can tell just by looking the first method i used was to take the say Fe2O3 i would put the 2 from the iron as the oxygen ion charge and the 3 for the oxygen as the iron ion charge Link to comment Share on other sites More sharing options...
Borek Posted May 14, 2005 Share Posted May 14, 2005 You can try to use periodic table to predict charge at best - there are nasty irregularities. But if you have no idea what the charge should be periodic table is better than nothing.
