Answer the following questions about quantum numbers and electron configurations. a) Identify the sublevels with the following combinations of quantum numbers and arrange then in order of increasing energy in an atom of Sg (Seaborgium, element 106)
n = 4,1 = 3 n=2,1 = 1 n=6,1 = 2 n= 7,1 = 0
b) Draw the orbital filling diagram for an atom of Sn and identify the valence electrons in the diagram.
c) Tin forms two stable ions, Sn² and Sn" Draw the orbital filling diagrams for the two ions of tin and explain how you decided which electrons were involved in the formation of the ions.
d) Is it possible for a neutral atom with an even number of electrons to have any unpaired electrons? Explain and provide an example with an orbital filling diagram to support your claim.
