If it is classified as metalloid, carbon and phosphorus must be also. Naming Se as metalloid and C and P only as nonmetal is inappriopiate and flawful. Se, C and P have very similar metallic properties. Iodine can also be named as metalloid. Generally, selenium (such as carbon, phosphorus and iodine) is considered nonmetal.
