It has 105 electrons and a +1 charge. Therefore, it must have 106 protons in its nucleus.

So, by definition, your unknown compound has #Z# (the atomic number) = 106. That is something transuranic, which you will have to look up on your Periodic Table! Would you report the result back here?

Keep in mind that this quote regarding the number of neutrons is just for show!
