Ions usually have the same electron configuration as the nearest noble gas on the periodic table. How could you use this information to predict the ions that would form for each element in a group (column) of the periodic table?

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. the only problem is that you do not know what element will form. by your previous calculations you know that you will have 6.3 moles of product. when it is complete, you weigh it and determine you have 604.4 grams. what element have you produced?
