Average Graduate Management Admission Test (GMAT) scores can be a good indicator of student quality -- often, schools with higher average GMAT scores are recognized more broadly for the quality of their graduates. The best place to start is www.mba.com/military.
For example, FeSO 4 is named iron(2+) sulfate (with the 2+ charge on the Fe2+ ions balancing the 2â charge on the sulfate ion), whereas Fe 2 (SO 4) 3 is named iron(3+) sulfate (because the two iron ions in each formula unit each have a charge of 3+, to balance the 2â on each of the three sulfate ions).
There are additional names used for ions with multiple charges. For example, an ion with a â2 charge is known as a dianion and an ion with a +2 charge is known as a dication. A zwitterion is a neutral molecule with positive and negative charges at different locations within that molecule.
