El boro es un elemento químico de la tabla periódica de los elementos que tiene el símbolo B y número atómico 5, su masa es de 10,811. Es un elemento metaloide, semiconductor, trivalente que existe abundantemente en el mineral bórax. Hay dos alótropos del boro; el boro amorfo es un polvo marrón, pero el boro metálico es negro. La forma metálica es dura (9,5 en la escala de Mohs) y es un mal conductor a temperatura ambiente. No se ha encontrado libre en la naturaleza.
