Boron - Wikipedia

WebSome elements may act as either cation or anion, depending on the electronegativity of the other element they bond to. In the borate anion, boron acts as a cation because oxygen is more electronegative than boron. In a boride, where boron bonds with a less electronegative element (e.d. silicon boride SiB3, and SiB6), boron acts as an anion.
