Valency of Elements
- Valency is the combining power of an element, typically measured by the number of hydrogen atoms it can combine with or displace to form a compound.
- Different elements have different valencies based on their ability to gain, lose, or share electrons to achieve a stable electronic configuration.
EXPLANATION:
- Carbon (C): Carbon typically has a valency of 4 because it can form four covalent bonds to achieve a stable electronic configuration (e.g., CH4).
- Oxygen (O): Oxygen typically has a valency of 2 because it needs two additional electrons to complete its outer shell (e.g., H2O).
- Nitrogen (N): Nitrogen typically has a valency of 3 because it needs three additional electrons to complete its outer shell (e.g., NH3).
- Sodium (Na): Sodium typically has a valency of 1 because it can lose one electron to achieve a stable electronic configuration (e.g., NaCl).
- From the above, it is clear that the element with a valency of 3 is Nitrogen (N).
Therefore, among the given options, Nitrogen has a valency of 3.
