I can't do this problem at all, can anyone help? Thanks.(adsbygoogle = window.adsbygoogle || []).push({});

During a trip to Roswell, New Mexico, you find yourself at a cocktail party

with aliens from another universe. You are at a loss for conversation so you offer to

reconstruct the periodic table from memory (chemistry being the most exciting thing you

can think of). The aliens are stupefied at your choice of conversation, but inform you that

in their universe, certain key rules governing the properties of atoms are different. Not

wishing to offend your charming hosts, you naturally take their physical laws into

consideration. They are:

• We have the same rules for n and l

• The only allowed values for ml are from −2l to +2l

• Only one value is allowed for ms , that is, each orbital may hold only 1 electron.

• We have the same rule for orbital energies (i.e. 4s lower in energy than 3d, etc.)

Use the rules above to answer the following questions:

a. What is the maximum number of electrons held in each alien quantum

level, n, for n = 1 through n = 6?

b. List all the electron configurations for the alien version of the elements

from Carbon through Vanadium. Assume each element still has the same number

of electrons.

c. What are the first 4 alien halogen elements?
