Answer 2

Statement 1: Both chlorine and nitrogen are nonmetals and gases, but the reactivity of nitrogen is higher than that of chlorine.

This statement is incorrect. While both chlorine and nitrogen are nonmetals and gases, the reactivity of chlorine is actually higher than that of nitrogen. Chlorine is a highly reactive element and readily forms compounds with other elements. Nitrogen, on the other hand, is relatively unreactive and forms compounds under specific conditions.

Statement 2: Despite sodium and phosphorus being in the third period, phosphorus has a high electron affinity.

This statement is correct. Despite sodium and phosphorus being in the same period (the third period) on the periodic table, phosphorus has a higher electron affinity compared to sodium. Electron affinity refers to the energy change that occurs when an atom gains an electron. Phosphorus has a higher electron affinity because it has a greater tendency to gain electrons and form negative ions compared to sodium.

Statement 3: The atomic radius of lithium is larger than the atomic radius of chlorine.

This statement is correct. The atomic radius of lithium is indeed larger than the atomic radius of chlorine. Atomic radius refers to the size of an atom, and it generally decreases across a period from left to right on the periodic table. Since lithium is located to the left of chlorine in the second period, it has a larger atomic radius than chlorine.

Statement 4: Nitrogen is a reducing agent, and lithium is an oxidizing agent.

This statement is incorrect. Nitrogen is not typically considered a reducing agent, but rather an inert gas due to its low reactivity. On the other hand, lithium is a highly reactive metal and is often used as a reducing agent in various chemical reactions. Therefore, the roles of nitrogen and lithium as reducing or oxidizing agents are opposite to what the statement suggests. To summarize: - Statement 1: Incorrect. The reactivity of chlorine is higher than that of nitrogen. - Statement 2: Correct. Phosphorus has a higher electron affinity compared to sodium. - Statement 3: Correct. The atomic radius of lithium is larger than the atomic radius of chlorine. - Statement 4: Incorrect. Nitrogen is not a reducing agent, but lithium is.
