Explain in detail what causes the color to change when testing different elements in a gas tube or under a flame. Explain what is happening to the electrons specifically that causes the color/light we see.

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.

Exothermic,  physical change after it is already baked
