🤓 Based on our data, we think this question is relevant for Professor Wade's class at OSU.
We’re being asked to arrange the given isoelectronic series in order of decreasing ionic 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.
Arrange the following isoelectronic series in order of decreasing radius:
F-, N3-, O2-, Mg2+, Na+
Rank ions from largest to smallest.
