To determine the position of elements 'X', 'Y', and 'Z' in the Modern Periodic Table based on their atomic numbers (7, 8, and 9), we can follow these steps: ### Step 1: Identify the Elements - **Element X** has an atomic number of 7. This corresponds to **Nitrogen (N)**. - **Element Y** has an atomic number of 8. This corresponds to **Oxygen (O)**. - **Element Z** has an atomic number of 9. This corresponds to **Fluorine (F)**. ### Step 2: Determine the Period Number ...
