To determine which two elements would bond together based on their ionic charges, we first need to consider the common ionic charges of each element:
- **Calcium (Ca)** typically forms a +2 charge (Ca²⁺).
- **Potassium (K)** typically forms a +1 charge (K⁺).
- **Iodine (I)** typically forms a -1 charge (I⁻).
- **Neon (Ne)** is a noble gas and has a stable electron configuration, so it does not typically form ions.
Now, let's analyze the pairs:
1. **Calcium and potassium**: Both are metals and can form positive ions, but they do not bond to each other since they both have positive charges.
2. **Potassium and iodine**: Potassium can form K⁺ (positive charge) and iodine can form I⁻ (negative charge). These two can bond because opposite charges attract.
3. **Calcium and neon**: Calcium can form Ca²⁺, but neon does not form ions, so they do not bond.
4. **Potassium and neon**: Similar to the previous pair, potassium can form K⁺, but neon does not form ions, so they do not bond.
Based on the analysis, the pair that would bond together based on their ionic charges is **potassium and iodine**.
- **Calcium (Ca)** typically forms a +2 charge (Ca²⁺).
- **Potassium (K)** typically forms a +1 charge (K⁺).
- **Iodine (I)** typically forms a -1 charge (I⁻).
- **Neon (Ne)** is a noble gas and has a stable electron configuration, so it does not typically form ions.
Now, let's analyze the pairs:
1. **Calcium and potassium**: Both are metals and can form positive ions, but they do not bond to each other since they both have positive charges.
2. **Potassium and iodine**: Potassium can form K⁺ (positive charge) and iodine can form I⁻ (negative charge). These two can bond because opposite charges attract.
3. **Calcium and neon**: Calcium can form Ca²⁺, but neon does not form ions, so they do not bond.
4. **Potassium and neon**: Similar to the previous pair, potassium can form K⁺, but neon does not form ions, so they do not bond.
Based on the analysis, the pair that would bond together based on their ionic charges is **potassium and iodine**.
