which element will form the ion with the largest ionic radius? mg al na
Answer
# Explanation:
## Step1: Analyze the charge of ions
- Na forms \(Na^+\) (loses 1 electron).
- Mg forms \(Mg^{2 +}\) (loses 2 electrons).
- Al forms \(Al^{3+}\) (loses 3 electrons).
## Step2: Apply the rule of ionic radius for isoelectronic species
When ions are isoelectronic (have the same number of electrons), the ion with the smallest positive charge has the largest ionic radius. Among \(Na^+\), \(Mg^{2+}\), and \(Al^{3+}\), \(Na^+\) has the smallest positive charge.
# Answer:
Na
