According to the Brønsted-Lowry definition, which is the best description of a base? A An electron donor
B A proton acceptor
C Having hydroxide ions in its formula
D Producing hydroxide ions in aqueous solution

B is the correct answer i believe

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
