Relating to or containing columbium (niobium); also relating to the element in its chemical compounds.
From 'columbium' (the former name for niobium, element 41) plus the adjective suffix '-ic.' Columbium was named after Columbia as a patriotic American reference when the element was first isolated.
Niobium was renamed from columbium because scientists needed one international name, but many American texts still call it columbium—this shows how science has to agree on names across countries, like how everyone calls the element 'oxygen,' not just their own language's version!
