Can someone tell me, for DAT purposes, what elements are considered metalloids and if they are also known as "semi-metals"??


My text book has them listed as B,Si,Ge,As,Sb,Te

But I have also seen lists including Po and At or not including them.

Can someone please help me out?

I believe that Po is a metalloid and At is not. All metalloids are semi-metals since they have properties similar to metals and nonmetals.
