How does catalysts make its way to common usage?​

A catalyst affects a chemical reaction by accelerating it. It also offers an alternative way for the reaction to happen that lowers the amount of energy needed.

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.
