Element Group 15 - Nitrogen Family Facts

Arsenic and antimony are metalloids. Bismuth is a metal. Except for nitrogen, the elements are solid at room temperature. Element density increases moving down the family. Except for nitrogen and bismuth, the elements exist in two or more allotropic forms. Nitrogen family elements display a wide range of physical and chemical properties.

Chemistry of Arsenic (Z=33) - Chemistry LibreTexts
