🤓 Based on our data, we think this question is relevant for Professor Smith's class at UH.
We’re being asked to determine the ion with the smallest radius.
Recall that ionic radius is the size of an ion. The trend for ionic radius is as follows: it increases from right to left and down a period in the periodic table. Ionic radius also increases with increasing number of electrons.
For this problem, we need to do the following:
Step 1: Determine the electrons in each species.
Step 2: Compare the charges if they are isoelectronic.
Which ion has the smallest radius?
