The correct Answer is:
To analyze the statements regarding hydrogen and its position in the periodic table, we can break down the solution step by step. ### Step 1: Evaluate Statement 1 **Statement 1:** "Long form of periodic table exactly explains the position of hydrogen." - The long form of the periodic table places hydrogen at the top of Group 1 (alkali metals) and Group 17 (halogens). - Hydrogen has properties similar to both groups: it can lose an electron like alkali metals (forming H⁺ ions) and can gain an electron like halogens (forming H⁻ ions). - Therefore, the position of hydrogen is ambiguous as it does not fit neatly into either group. **Conclusion for Statement 1:** This statement is **false**. ### Step 2: Evaluate Statement 2 **Statement 2:** "Hydrogen is the most abundant element in the universe." - Hydrogen is indeed the most abundant element, making up about 75% of the elemental mass of the universe. - It is primarily found in stars, including our Sun, where it undergoes nuclear fusion to form helium. **Conclusion for Statement 2:** This statement is **true**. ### Step 3: Analyze the Relationship Between the Two Statements - Since Statement 1 is false and Statement 2 is true, Statement 2 does not explain Statement 1. - Therefore, the correct answer is that Statement 1 is false, and Statement 2 is true. ### Final Conclusion The correct option is that **Statement 1 is false and Statement 2 is true**. ---
