### Exercise: Identifying Correct Statements on Atomic and Ionic SizesPlease select the correct statements regarding the comparative sizes of atoms and ions from the options below. Check all that apply.- [ ] Cl⁻ is smaller than Cl- [ ] Na is smaller than Na⁺- [ ] Au⁺ is smaller than Au³⁺- [ ] O²⁻ is smaller than S²⁻- [ ] Mg²⁺ is smaller than Al³⁺- [ ] Au³⁺ is smaller than Au⁺- [ ] Al³⁺ is smaller than Mg²⁺- [ ] Na⁺ is smaller than Na- [x] Cl is smaller than Cl⁻- [ ] S²⁻ is smaller than O²⁻### Explanation of Concepts- **Ionic Radius vs. Atomic Radius**: Anions (negatively charged ions) are generally larger than their neutral atoms, while cations (positively charged ions) are smaller than their neutral atoms. This occurs because the addition of electrons in anions increases electron-electron repulsion, while the removal of electrons in cations decreases it, allowing the atomic nucleus to pull the remaining electrons closer.- **Comparison of Ionic Sizes with Different Charges**: For ions with the same number of electrons (isoelectronic), a higher positive charge results in a smaller ion due to increased nuclear attraction for electrons. Conversely, a higher negative charge usually leads to a larger ion.

Atomic radius: The atomic radius of an element decreases as we move from left to right in a period…
