2018-10-09 · Transition metals are a subcategory of metals. Metalloids are intermediate chemical elements to that of metals and nonmetals according to their chemical and physical properties. The key difference between transition metals and metalloids is that the transition metals are chemical elements which have atoms with unpaired d electrons whereas the A metalloid is an element that possesses a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals, and which is therefore hard to classify as either a metal or a nonmetal. 2020-01-17 · In this way, is boron a metal or nonmetal or metalloid?
