Ionic Size Doubt Why is the size of Al3+ less than that of Li+?

2 mainly math formatting, some grammar

Why is it so that the size of ${Al}^{3+}$$\ce{Al^{3+}}$ is lesser than ${Li}^{+}$ $\ce{Li+}$?

I'm a bit confused forabout this one as in Aluminium the aluminium(3+III) ion, there are is composed of 10 electrons and 13 protons, while in Lithium (+)the lithium ion, there are has only 2 electrons and 3 protons.

Electronic Configurationconfiguration of ${Al}^{3+}$ will be$\ce{Al^{3+}}$ is $1s^2 2s^2 2p^6$$\mathrm{1s^2 2s^2 2p^6}$ and that of ${Li}^{+}$ will be $1s^2$$\ce{Li+}$ is $\mathrm{1s^2}$. Now

Now,doesn't this seem much it seems obvious that the size of ${Al}^{3+}$$\ce{Al^{3+}}$ should be greater than that of ${Li}^{+}$$\ce{Li+}$, but only the inverseit is true of thisactually the other way around. Why is it so?Why is this? I think that it is a kind of exception, but if any oneanyone can explain the reason behind this, it will help me in my upcoming Teststests.
