Question

If you maximize the unshared electrons in the boron atom, the electron configuration is?

i know the electron configuration at ground state is 1S2 2S2 2P1

but when it maximizes unshared electrons i don't understand how it affects the configuration

Answer 1

I think the question means that B will have 1s2 2s1 2p2 and that's how you get BF3, BH3, etc but I must confess the wording is confusing.
