**Question 14** **Fill in the blank spaces:** | Symbol | Protons | Neutrons | Electrons | |-------------|---------|----------|-----------| | \(_{29}^{65}\text{Cu}^{2+}\) | 23 | 27 | 19 | | | | | | | 119 | 50 | | 46 | | | | | | **Explanation of the Table:** This table presents information about the atomic composition of certain elements/isotopes. The columns specify: - **Symbol**: Represents the chemical representation of the element or isotope, including atomic number and charge. - **Protons**: The number of protons in the nucleus, determining the element's identity. - **Neutrons**: The number of neutrons in the nucleus, which with protons gives the atomic mass. - **Electrons**: The number of electrons in the atom or ion, influencing the charge. **Diagram Explanation:** 1. For \( _{29}^{65}\text{Cu}^{2+} \): - Atomic number (subscript) indicates 29 protons in copper. - It has 23 protons listed (possible error or needs adjustment). - Neutron count is 27. - It has 19 electrons, implying it lost 2 electrons (hence the 2+ charge). 2. For the row with mass number 119: - Contains 50 protons, suggesting the element is tin (Sn). - Electron count is 46, indicating a 4+ charge. - The neutron count is missing and needs calculating: Neutrons = Mass Number (119) - Protons (50) = 69 neutrons.
