Group 15 Elements Quiz

Study Notes

Electronegativity Trend Down the Group

Electronegativity decreases down the group due to increased atomic size and electron shielding.
Larger atoms hold their valence electrons less tightly, making them less effective at attracting electrons from other atoms.

State of Dinitrogen

Dinitrogen (N₂) exists as a diatomic gaseous molecule at room temperature.
It is colorless, odorless, and accounts for approximately 78% of Earth's atmosphere.

Boiling Points Trend in the Group

Boiling points generally increase down the group due to greater molecular weight and van der Waals forces.
For example, while nitrogen has a low boiling point, heavier group elements have significantly higher boiling points due to increased intermolecular attractions.

Melting Points Trend from Nitrogen to Bismuth

Melting points show a general upward trend from nitrogen to bismuth, influenced by stronger metallic bonds in heavier elements.
Exceptions may occur due to specific crystal structures or bonding variations impacting the melting point.

Trend of Stability of +5 Oxidation State Down the Group

Stability of +5 oxidation state decreases down the group as the ability to form stable bonds with oxygen diminishes.
Heavier group elements are less likely to maintain a high oxidation state, leading to more prevalent lower oxidation states.
