Question
### What Does "X" Represent in the Following Symbol? To understand what element "X" represents in the symbol below, we need to decode the symbol using the atomic number and mass number given: \[ _{14}^{28}X \] In this notation: - The bottom number (14) represents the **atomic number**, which is the number of protons in the nucleus of the atom. - The top number (28) represents the **mass number**, which is the total number of protons and neutrons in the nucleus. Using the **atomic number (14)**, we can identify the element from the periodic table. ### Options: - **Silicon** - **Sulfur** - **Nickel** - **Nitrogen** Based on the atomic number: - **Silicon (Si)** has an atomic number of 14. ### Conclusion: Given that the atomic number 14 corresponds to silicon (Si), "X" represents: \[ \boxed{\text{silicon}} \]
