Group 5 refers to a category of elements in the periodic table, specifically the group that includes nitrogen, phosphorus, arsenic, antimony, and bismuth. These elements share similar chemical properties, such as the ability to form three or five bonds with other elements. They are known for their diverse applications in various fields, including agriculture and electronics. The elements in Group 5 are characterized by their varying states of matter at room temperature. For instance, nitrogen is a gas, while bismuth is a solid. This group also includes metalloids like arsenic and antimony, which exhibit properties of both metals and nonmetals, making them useful in different industrial processes.
