The correct Answer is:
To solve the question, we need to analyze both statements regarding nitrogen and valency. ### Step 1: Analyze Statement-1 **Statement-1:** Nitrogen can form a maximum of four bonds with hydrogen. - Nitrogen has an atomic number of 7, which means it has 7 electrons. The electronic configuration is 1s² 2s² 2p³. - In the outer shell (2s² 2p³), nitrogen has 5 valence electrons. - To achieve a stable octet, nitrogen needs 3 more electrons. Therefore, nitrogen can form a maximum of 3 covalent bonds with hydrogen, as seen in ammonia (NH₃). - Although nitrogen can form four bonds in the ammonium ion (NH₄⁺), this is under a specific condition (the presence of a positive charge) and is not the general case. **Conclusion:** Statement-1 is incorrect. ### Step 2: Analyze Statement-2 **Statement-2:** Valency is the combining capacity of an element and it is always constant. - Valency is defined as the ability of an atom to bond with other atoms, which is determined by the number of electrons an atom can gain, lose, or share. - For example, sodium (Na) has a valency of +1 because it can lose one electron, while chlorine (Cl) has a valency of -1 because it can gain one electron. - The valency of an element remains constant for a given oxidation state, meaning it does not change under normal circumstances. **Conclusion:** Statement-2 is correct. ### Final Conclusion - Statement-1 is incorrect. - Statement-2 is correct. The correct option based on the analysis is that Statement-1 is false and Statement-2 is true. ---
