How many orbitals are in the p sublevel?
A 2
B 3
C 4
D 5
A?
Sublevels are s,p,d,f etc. There are 1,3,5,7 orbitals in each and when each is filled can hold 2,6,10,14 electrons
Place gamma rays, infrared, microwaves, radio waves, ultraviolet, visible light, and x-rays in order from largest wavelength to smallest wavelength.
A Gamma rays, infrared, microwaves, radio waves, ultraviolet, visible light, and x-rays.
B Radio waves, x-rays, microwaves, infrared, ultraviolet, visible light, and gamma rays.
C Radio waves, microwaves, infrared, x-rays, ultraviolet, visible light, and gamma rays.
D Radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays.
D?
I agree
True or false: The wavelength of light emitted by a substance when its atoms absorb and release energy is diagnostic of the chemical composition of that substance.
True
False

I think this problem can be misinterpreted quite easily and I could make a case for either answer being correct. Initially I agreed with you; however, on re-reading about "diagnostic of the chemical composition of that SUBSTANCE". I am convinced the answer is false. For example, if I subject Na2SO4 to spectroscopic analysis, I can easily tell you Na ions are there BUT I can't tell you the identity of the anion. On the other side of the coin, if I can hand pick the compound AND the method, I might use infrared (same principles) and I could distinguish, for example, between Na2SO4 and KCl; therefore, under some conditions this could be a true statement. I assume this is a lower level class so I would go with false
