# 2-D atoms!

**Chemistry**Level pending

Assume we move to a 2 dimensional world, where the periodic table is based on 3 quantum numbers,

n= 1,2,3,4,.....

m*= -(n-1).. -2,-1 ,0 ,1 ,2, ..(n-1)

s = +0.5 or -0.5

Such that m* plays the combined role of both m and l (3-D quantum numbers)

Assume that in this 2-D world, chemical and physical experience from our world is applicable.

Knowing this, in the 2-D world how does the octet rule and the pseudo-octet rule change?

If the number electrons to complete the new rule and new pseudo-rule are *n* and *m* respectively,

What is the value of *n*+*m* =
