Boron is classified as a metalloid while the rest, with the possible exception of ununtrium, are considered post-transition metals. Ununtrium has not yet been confirmed to be post-transition, due to relativistic effects, might not turn out to be one.he elements in group 13 are also capable of forming stable compounds with the halogens, usually with the formula MX 3 (where M is a boron-group element and X is a halogen.) The only exception to this is thallium(III) iodide.
