Ionic bonds are typically between metals and non-metals.
Beryllium is a Metal, and Nitrogen is a non metal.
Why is this book showing Be3N2 as having a covalent bond?
Is this an exception to this general rule?

its ionic the diagram is probably showing the lattice structure or something, ironic or covalent bonding is determined by the difference in electronegavitivy
>>7972485
did you even fucking read the book?
Beryllinium and Boron are the only two natural exemptions from the octet rule

This is literally the first chapter discussing ionic and covalent bonds.
The only explanation offered was that it's a non-metallic bond, and therefore molecular. Obviously I'm confused because I understand Beryllium as a metal. I understand there's exceptions, but they haven't been mentioned in any specifics yet

It is a metal...

It's easiest to think of chemistry concepts in a distilled, most basic way, like:
Ionic bonds = big difference in electronegativity that allows two species to bond trough a complete transfer of electrons.
Covalent bonds = negligible difference in electronegativity, bonding occurs through sharing of valence electrons to stabilize the compound.
Don't get too hung up trying to apply absolute statements, like "always between a metal and non-metal, etc." Although these are often true, there are always exceptions, like beryllium nitride (and other beryllium compounds).
Beryllium is smaller than the rest of the group two metals and is electronegative enough that it won't dish out its electrons to form ionic bonds -- but will share them to form covalent ones.

good post

Learn to Pauling's Electronegativity values desu

I'm not sure if noone has pointed out that this is wrong because its so obvious
