If two elements have the same value of the quantum number n and different l, ml and ms then they must be in: *The same orbital, but different level and sub level.
*Different level, sublevel and orbital
*The same level, sub level and orbital.
*The same level, but different sublevel and orbital
*The same sub-level and orbital but different level.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
