In the real world ms (the electron spin quantum number) has onlytwo values. For giggles, let’s assume that in the galaxy next doorms can have four values instead of two (let’s say -1, -1/2, +1/2,and +1). All of the other normal rules apply for the quantumnumbers n, l, and ml. Answer the following questions for theseassumptions.
A) How many electrons could each orbital hold?
B) How many elements would be contained in the first and secondperiods of the periodic table?
C) How many elements would be contained in the first transitionmetal series?
D) How many electrons would the set of 4f orbitals be able tohold?

2. Use symmetry to consider the bonding in thebenzenemolecule, C6H6. You needn't gettoocarried away with it. You can assume, for instance, that asigmabonding network will hold the planar molecule together. Focusyourattention instead on the pi bonding that exists between the6carbon atoms. A reasonable basis set would be the 6 porbitals,perpendicular to the moleculare plane, that mightparticipate insuch bonding.
Your answer should include: the number of moleculeorbitalsexpected for each of the irreducible representation ofthemolecule's point group; descriptions (equations and sketches)ofsymmetry orbitals that could be used to form thosemolecularorbitals; and your best estimate of the resulting energyleveldiagram.
Ok, the π bonding in benzene is written up in many,manyplaces. I hope you"ve been able to check your results. Nowtrythese additional questions:
What happens to the π molecularorbitals if a heteroatom isinserted into the ring, turning benzeneinto pyridine?
What happens if a second nitrogen replaces acarbon in thepara-position in pyridine?
What would removing one electron frombenzene do to theenergies of its π orbitals?
N.B. I have answered most part of the above questionexceptthat the ones mark in RED is not done yet. So, can you helpmeplease?

PLEASE READ THE WHOLE QUESTION

SIDE NOTE:

IN BIZARRO WORLD, the S subshell can only hold 2 electrons, the P subshell can only hold 4 electrons, the D subshellf can only hole 6 electrons and the F subshell can only hold 8 electrons.

We are trying to create a new periodic table based on these assumptions.

The modern periodic table is arranged the way it is because of quantum mechanics. That is, there are sections for each subshell, and the number of columns in each section are dictated by the number of electrons allowed in each subshell.

Imagine that you have entered an alternate dimension where the laws of quantum mechanics are different.The elements have the same symbols and even the same number of protons, neutrons, and electrons, but their arrangement on the Bizarro Periodic Table will differ greatly from our own. They use the same letters to designate the subshells (s, p, d, and f) even though their number of orbitals differ.

Consider these rules for the quantum numbers in Bizarro World:

n can be any whole number from 1 to infinity (this is the same as our world.)

l can be integer values from 0 to n.

ml can only go from 0 to l.

ms is the same as in our world (± ½)

Answer the following questions:

What subshells are allowed in the Bizzaro first shell? The second shell? The third shell? The fourth shell?

How many orbitals and electrons fit into the Bizarro s subshell? The p subshell? The d subshell? The fsubshell?

Based on this information, please draw what the Bizzaro Periodic Table might look like.

Draw the first 6 rows and include the s, p, d, and f subshell areas (include the f block between the s and dblocks, not separated).

Remember that the (n-1) rule for d subshells and (n-2) rule for f subshells still applies.

You don’t have to list the atomic numbers or masses in each box, just the element symbols will be fine.

As a hint: the 6th row of your Bizarro Periodic Table should end with element 76, Osmium.

What elements would make up the Bizarro Noble gases?

What elements would make up the Bizarro Halogens?

How many total electrons would it take to fill the valence shell for any given atom?

Please give the Bizzaro electron configuration for the following elements. You may use Bizarro noble gas abbreviations for the core electrons if you like.
