The question asks you write out the abbreviated electron configuration of Te^-2, the solutions manual states that the answer is [Xe], however is the answer still valid as [Kr] 5s^2 4d^10 5p^6 (with no unpaired electrons)?
Hi! To be safe you would probably want to write [Xe] as opposed to the other electron configuration. Typically when writing electron configurations you have to start with the noble gas in the prior period that is the closest to the element in question. This is probably where your answer is stemming from. Since Te^-2 has the same amount of electrons as Xe, it is a different case in which an electron configuration can be expressed by the noble gas in the same period. Therefore, it should be expressed as [Xe]. The other configuration technically isn't wrong, but it is not as concise as [Xe] and Xe is the closest noble gas that is representative of Te^-2. Hope that helped a little.
