“12th Class Chemistry Chapter 4 Quiz: Group VA and VIA Elements” helps students learn chemical and physical properties of elements of Group 15 (VA) and 16 (VIA) of the periodic table. This group contains very essential nonmetals and metalloids like nitrogen, phosphorus, oxygen, and sulfur, which are very important to be prepared for MDCAT. Improve your knowledge with our free MDCAT Quiz and flashcards to particularly strengthen your command over these groups.
Group VA Elements (Nitrogen Family)
The Group VA elements are Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), and Bismuth (Bi). The elements show a change from nonmetallic to metallic properties down the group.
Physical and Chemical Properties
Atomic and Ionic Radii: Atomic size increases down the group due to additional electron shells, while electronegativity decreases.
Ionization Energy: Ionization energy is high at the top of the group and decreases as metallic character increases.
OXIDATION STATES: The common oxidation states vary from −3 to +5. The stability of the +5 oxidation state decreases down the group due to the inert pair effect.
Reactivity: Nitrogen forms a wide variety of compounds, such as ammonia (NH₃), nitric acid (HNO₃), and nitrogen oxides. Phosphorus is obtained in a few allotropes: white, red, and black phosphorus, which react easily with halogens and oxygen.
