Could this be the electron configuration of a bromine atom?
[Ar]4s^2 3d^10 4p^5 4d^1
yes, if an electron was excited?
500
Why do large molecules have low ionization energies?
Their electrons are farther away from their nucleus; therefore, there is less attraction holding them in place and their electrons can be removed relatively easily.
500
What causes the exceptions for the ionization energy periodic trend?
What about the electron affinity periodic trend?
2A and 5A have half-filled or filled orbitals; therefore, they don't want to give up an electron and lose stability.
2A and 5A also don't want to gain an electron, which would also decrease their stability.
