Transcribed Image Text:**Question:**
Write the following from largest to smallest size. (Use periodic trends.)
(a) Ca, Mg²⁺, Ca²⁺
**Description:**
This exercise requires an understanding of periodic trends and the size of atoms and ions. You are asked to compare the size of calcium (Ca), magnesium ion (Mg²⁺), and calcium ion (Ca²⁺).
**Explanation:**
- **Calcium (Ca):** A neutral atom with a complete set of electrons in its outermost shell.
- **Magnesium ion (Mg²⁺):** A magnesium atom that has lost two electrons, resulting in a smaller ionic radius due to the reduced electron-electron repulsion.
- **Calcium ion (Ca²⁺):** A calcium atom that has also lost two electrons, leading to a smaller size compared to the neutral calcium atom.
**Tips:**
When comparing sizes, remember:
- Neutral atoms are larger than their cations.
- Among cations, the ion with fewer protons but the same electron configuration is larger.
Use these principles to order the given atoms/ions from largest to smallest.
