Do All B Group Elements Form More Than One Charge - For example, iron atoms can form 2+ cations or 3+ cations. Define the two types of ions. For groups 15 through 17, the charge is usually negative because these elements are more likely to gain than lose. A few elements, all of which are metals, can form more than one possible charge. Use lewis diagrams to illustrate.
