Study Notes

Group 5A Elements

Elements in this group: Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), Bismuth (Bi), Moscovium (Mc)
Electronic configuration: ns²np³
Reactivity: Generally less reactive than halogens, but reactive when combined with oxygen
Physical States: Nitrogen is a gas, phosphorus is a solid, arsenic is a metalloid, antimony and bismuth are metals, Moscovium is a radioactive metal
Uses: Nitrogen is used in fertilizers, phosphorus is used in fertilizers and detergents, arsenic is used in semiconductors, antimony is used in alloys, bismuth is used in alloys
Occurrence: Nitrogen is the most abundant element in the atmosphere, phosphorus is found in phosphate rocks, arsenic is found in various minerals, antimony is found in combination with sulfur, bismuth is found in minerals. Moscovium is produced in labs.

Properties of Nitrogen

Physical properties: Colourless odourless gas.
Chemical properties: Very inert gas. Strong triple bond makes nitrogen very stable (N₂). Inert in normal conditions, but can react at high temperatures.
Important point: Nitrogen is unreactive, and largely inert.
Occurrence: Most abundant gas in air.
Biological importance: Component of amino acids, proteins, nucleic acids.

Properties of Phosphorus

Physical properties: Solid, non-metal, can occur in different allotropic forms (white, red, black).
Chemical properties: Reactive non-metal, easily oxidized.
Applications: Essential for living organisms, used in fertilizers and detergents.
Occurrence: Common in phosphate rocks.

Properties of Arsenic, Antimony, Bismuth

Physical properties: Arsenic is a metalloid, antimony and bismuth are metals.
Chemical properties: Relatively reactive, but less reactive than halogens.
Applications: Used in semiconductors, alloys; Antimony in flame-retardant materials, bismuth in low-melting alloys and medical applications.

Other notes

Presence in the atmosphere: Nitrogen is the largest component of the atmosphere.
Reactions with other elements: Nitrogen, phosphorus, arsenic, antimony, bismuth can all form compounds with other elements.
Biological role: These elements play important roles in living systems.
Environmental concerns: Phosphorus is a key nutrient in aquatic ecosystems, but excess phosphorus can lead to eutrophication (harmful algal blooms).
Practical/Laboratory Considerations: Caution must be exercised while handling these elements due to their potential reactivity.
