Il boro è l'elemento chimico della tavola periodica degli elementi che ha numero atomico 5 e simbolo B. È il primo elemento del gruppo 13 del sistema periodico, inaugurando così il blocco p del sistema periodico. È un semimetallo trivalente e si trova abbondantemente nel borace. Ci sono due allotropi del boro: il boro amorfo, che è una polvere marrone, e il boro metallico che è nero. La forma metallica è dura (9,3 sulla scala di Mohs) ed è una cattiva conduttrice a temperatura ambiente. Il boro non si trova libero in natura. Questo elemento ha proprietà e reattività simili al silicio ed è un semiconduttore (relazione diagonale).
