* Understanding Valency: Valency refers to the combining power of an element, essentially how many bonds an atom of that element can form.
* Structure of Pentoxide: Nitrogen pentoxide (N₂O₅) has the following structure:
- Two nitrogen atoms (N)
- Five oxygen atoms (O)
* Oxygen's Valency: Oxygen usually has a valency of 2 (it forms two bonds).
* Calculating Nitrogen's Valency:
- Each oxygen atom forms a single bond with each nitrogen atom.
- Since there are five oxygen atoms, each nitrogen atom forms five bonds.
- Therefore, the valency of nitrogen in N₂O₅ is 5.
Important Note: While the valency of nitrogen in N₂O₅ is 5, it's important to recognize that nitrogen can exhibit various valencies depending on the compound.
