Write equations that show the processes that describe the first, second, and third ionization energies of a boron atom. I got the first and second ionization correct but for some reason it keeps telling me that my equation for the third ionization is wrong and i dont know why, could someone please help! This is what i got but keeps telling me i am wrong B^+ ? B^3+ +e^-
