There are 117 known elements (up to 118 excluding 117 which has not been created as of yet). 17 are non-metals: H, He, C, N, O, F, Ne, P, S, Cl, Ar, Se, Br, Kr, I, Xe, and Rn 9 are metalloids: B, Si, Ge, As, Sb, Te, Po, At, Uuo* The remaining 91 are metals. *Ununoctium, Uuo, is predicted to be a metalloid but there is no experimental verification of this.
