Question

Previous Problem for Context

(1. The year is 2053, and the researchers have been working hard on trying to fill up the next row of the periodic table. In particular, they are trying to determine all electronic properties of the element (potential name Eiteneerium, Ei) whose atomic number is 141. (Note: as of right now we do not think that anything beyond Z = 126 is stable, but in 2053... who knows).

A. Determine the electronic configuration of the last electron in Ei (no shortcuts).

B. Complete the “arrow” diagram (no shortcuts).

C. Write down the four quantum numbers of the last electron in Ei.

D. Determine the orbital momentum (L) for the last electron in Ei. Leave L in terms of h.)

End Previous Problem (I just need help with problem 2)

2. For the element Eiteneerium (Ei) described in the previous problem, you should have written n =7.

A. What would be the average orbital distance of an electron in n =7?

B. If this electron could transition down from n = 7 to any other energy level, what would be the largest wavelength and the shortest wavelength of the photon can be emitted? Reminder: Z = 141.

Answer 1

here the electronic configuration is based on aufbau principle. But when atomic number goes beyond 120, overlapping of shells occur.
