Question

Why is 4d10 not the answer? That is not the third row

 

 

 

--- ## Answer to Problem 70E The element is found to be bromine and the most stable ion of bromine is Br⁻. ## Explanation of Solution Atomic number given is 35. From the periodic table we can identify that the element with atomic number 35 is bromine (₃₅Br). Bromine: \[Ar\] 3d¹⁰ 4s² 4p⁵ The electronic configuration for bromine is given above. From which we can see that it is having an incomplete configuration. If bromine gains one more electron, it acquires a completely filled configuration. Hence, the most stable ion of bromine will be Br⁻. ---

### Ion Formation in Ionic Compounds Based on Atomic Numbers **Question 70:** For each of the following atomic numbers, use the periodic table to write the formula (including the charge) for the simple ion that the element is most likely to form in ionic compounds. #### Atomic Numbers: - **a. 13** - **b. 34** - **c. 56** - **d. 7** - **e. 87** - **f. 35** **Note:** The elements corresponding to these atomic numbers are: - 13 → Aluminum (Al) - 34 → Selenium (Se) - 56 → Barium (Ba) - 7 → Nitrogen (N) - 87 → Francium (Fr) - 35 → Bromine (Br) Utilizing the periodic table, the typical ionic charges for these elements are determined based on their group positions and electron configurations. Below is the list of the most likely simple ions each element forms: 1. **Aluminum (Al) - Atomic Number 13** - Likely Ion: Al³⁺ 2. **Selenium (Se) - Atomic Number 34** - Likely Ion: Se²⁻ 3. **Barium (Ba) - Atomic Number 56** - Likely Ion: Ba²⁺ 4. **Nitrogen (N) - Atomic Number 7** - Likely Ion: N³⁻ 5. **Francium (Fr) - Atomic Number 87** - Likely Ion: Fr¹⁺ 6. **Bromine (Br) - Atomic Number 35** - Likely Ion: Br¹⁻ By identifying the positions of these elements on the periodic table, their common ion charges can be deduced, providing insight into the type of ions they form in ionic compounds. --- **References and Copyright** *Unless otherwise noted, all art on this page is © Cengage Learning 2014.*
