The alkali metal ion with the smallest ionic size is Li+.

Here's why:

The size of an ion is determined by its atomic radius. In the periodic table, as you move down a group (column), the atomic radius increases. This is because each row adds a new electron shell.

The alkali metals are in the first group of the periodic table. From top to bottom, the order is: Li, Na, K, Rb, Cs.

So, Li+ is at the top of the group and has the fewest electron shells, making it the smallest alkali metal ion.
