Question

what is mean by pnicogenes? Related:  Group 15 Properties - The p block elements?

Answer

The 12-16 group compounds are prepared by combining group 12 and group 16 elements and the 13-15 group compounds are prepared by combining group 13 and group15 elements. These compounds are prepared to stimulate average valence of four as in Ge or Si .

Answer

A pnictogen /ˈnɪktədʒɨn/ is one of the chemical elements in group 15 of the periodic table. This group is also known as the nitrogen family. It consists of the elements nitrogen, phosphorus, arsenic, antimony, bismuth and the synthetic element ununpentium. In modern IUPAC notation, it is called Group 15. In CAS and the old IUPAC systems it was called Group VA and Group VB respectively. In the field of semiconductor physics, it is still usually called Group V. The 'five' in the historical names comes from the 'pentavalency' of nitrogen, reflected by the stoichiometry of compounds such as N₂O₅. The term pnictogen is derived from the Ancient Greek word πνίγειν meaning 'to choke', referring to the choking or stifling property of nitrogen gas.

Answer

What are Pnicogenes?
Pnicogenes are a group of compounds that contain elements from Group 15 of the periodic table, also known as the p block elements. These elements include nitrogen, phosphorus, arsenic, antimony, and bismuth.

Group 15 Properties
- Group 15 elements have a valency of 5, meaning they tend to form compounds with a covalency of 5.
- These elements typically form compounds with a -3 oxidation state, such as in the case of ammonia (NH3) or phosphine (PH3).
- The size of the atoms increases as you move down the group, leading to changes in their physical and chemical properties. For example, nitrogen is a gas at room temperature, while bismuth is a solid.
- Group 15 elements can form multiple bonds with other elements, such as in the case of nitrogen in N2 or phosphorus in P4.

Key Points
- Pnicogenes are compounds containing Group 15 elements.
- Group 15 elements have a valency of 5 and tend to form compounds with a covalency of 5.
- These elements typically exhibit a -3 oxidation state and can form multiple bonds with other elements.
- The properties of Group 15 elements change as you move down the group due to differences in atomic size.
