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:
Then, read the periodic table from left to right, beginning from radon.
As you see, to get to oganesson, we go through:
- The complete
#7s# orbital. The maximum number of electrons in the#s# orbital is#2# . It's full, so oganesson has#2# electrons in the#7s# orbital. - The complete
#5f# orbital (for the#f# orbitals, subtract#2# from the period number to get the energy level. So, for us, it would be#7-2=5# .) The maximum number of electrons in the#f# orbital series is#14# . It's full, so oganesson has#14# electrons in the#5f# orbital. - The complete
#6d# orbital. The maximum number of electrons in the#d# orbital series is#10# . It's full, so oganesson has#10# electrons in the#6d# orbital. - The complete
#7p# orbital. The maximum number of electrons in the#p# orbital series is#6# . It's full, so oganesson has#6# electrons in the#7p# orbital.
Put that information all together:
