Which type of bonding does Ba form upon solidification?

covalent network
ionic    (I know for fact this is not the correct answer, but not why)
metallic
molecular

I thought Ba was an Ionic solid. The only other reasonable choice I can come up with is metallic. Can anyone else confirm this, and point me to their source for the info?
