Question
**Q4) Consider the element Xy that has an atomic number of 56. If this element has the following data:** | | **Mass (amu)** | **Natural Abundance** | |------------|----------------|-----------------------| | **Xy1** | 95.34 amu | 45.00% | | **Xy2** | 104.3 amu | | a) Calculate the average mass of the element Xy. b) Calculate the number of protons, electrons, and neutrons that the element Xy has. --- **Instructions:** - To calculate the average mass of element Xy, use the formula that accounts for the different isotopic masses and their natural abundances. - Since the atomic number is 56, this represents the number of protons and, in a neutral atom, also the number of electrons. To find the number of neutrons, use the formula: neutrons = mass number - atomic number.

**Transcription of the Image:** --- **b) Calculate the number of protons, electrons and neutrons that the element Xy have.** **c) If the element Xy form an ion Xy^"-", is this element a metal or a non-metal? Explain your answer.** --- **Explanation of the Context:** In this part of an educational website focusing on chemistry, students are prompted to: 1. **Calculate Atomic Particles:** - Determine the number of protons, electrons, and neutrons for a given element (Xy). This typically involves understanding the atomic number and mass number of the element. 2. **Determine Metal or Non-Metal:** - Consider the formation of an ion (Xy^"-") and decide if the element is a metal or non-metal. Generally, non-metals tend to gain electrons and form negative ions. This task emphasizes understanding of atomic structure and characteristics that distinguish metals from non-metals.
