Los elementos de la tabla periódica se agrupan como metales, metaloides o semimetales y no metales. Some elements between the metals and non-metals in the periodic table have properties which are a mixture of the properties of metals and non-metals. For example, boron acts as a nonmetal when it reacts with sodium, but it acts as a metal when it reacts with fluorine. They are located to the right of the post-transition metals and to the left of the non-metals. Using it, you should be able to classify all the elements in different ways. Only the elements at or nea… Metalloids (7) Some books say the term Metalloid is out-dated. Phosphorus, tin, selenium and bismuth also have allotropes which display borderline behaviour. 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. These metals are very reactive, so chemists have to be very careful how they … The metalloids, also known as semimetals, are located along the staircase line that is in between the metals and nonmetals. The line begins at boron (B) and extends down to polonium (Po). The metalloids are a group of elements in the periodic table.
