The second to last shell would be n=6, and the last transition element in n=6 would be Mercury, (Hg), and it has 80 electrons, so that seems like it would be the correct answer. If you meant "in their second to last orbit", then the answer would be different.
The transition metals are able to put up to 32 electrons in their second to last shell.
32
Second shell has a maximum of 8 electrons.
8 electrons
8 (just in the second shell) but if you're counting all of the electrons, including the first shell, then there are 10 electrons all together. Eight Electrons are the maximum.
8
The maximum number of electrons in the second energy level of an atom is 8.
The maximum number is 8 electrons in the second shell.
Second shell has a maximum of 8 electrons.

The maximum number of electrons in the second energy level of an atom is 8.
First orbital can be occupied by a total of 2 electrons and the second orbital can be occupied by a total of 8 electrons. 1s^2 2s^2 2p^6 ( what element is this ? )
