According to the explanation given in our last session, now we have the following information about the last electron:
n = 6
l = 1
m = 0
s = +1/2
Now we know that this electron is located in the 6th shell, therefore the element is in the 6th period of the periodic table
l = 1, this means that the last orbital will be p
m = 0, this means that the electron is located in the middle of the orbital
s = +1/2, this means that the electron is pointing upwards
Gathering all these informations, we know have as the element in which this last electron belongs is Lead, Pb
