Explanation:
For oganesson, we should probably use noble gas notation (to indicate that it has the same electron configuration as that noble gas to a certain point) because it would get too long otherwise.
The closest noble gas to oganesson is radon. So, make that the first part of the answer:
PTable
Then, read the periodic table from left to right, beginning from radon.
PTable orbital mode
As you see, to get to oganesson, we go through:
- The complete
7s orbital. The maximum number of electrons in thes orbital is2 . It's full, so oganesson has2 electrons in the7s orbital. - The complete
5f orbital (for thef orbitals, subtract2 from the period number to get the energy level. So, for us, it would be7-2=5 .) The maximum number of electrons in thef orbital series is14 . It's full, so oganesson has14 electrons in the5f orbital. - The complete
6d orbital. The maximum number of electrons in thed orbital series is10 . It's full, so oganesson has10 electrons in the6d orbital. - The complete
7p orbital. The maximum number of electrons in thep orbital series is6 . It's full, so oganesson has6 electrons in the7p orbital.
Put that information all together:
