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

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

For the first question, the p sublevel can hold a maximum of 3 orbitals. Each orbital can hold a maximum of 2 electrons. So, the correct answer is B - 3.

To determine the order of different types of electromagnetic waves based on their wavelengths, you need to understand the electromagnetic spectrum. The electromagnetic spectrum includes gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves, and radio waves, in increasing order of wavelength.

So, the correct order from largest to smallest wavelength is:

B - Radio waves, x-rays, microwaves, infrared, ultraviolet, visible light, and gamma rays.

For the last question, 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.

The correct answer is True. The phenomenon is known as emission spectroscopy, where each element has its unique atomic emission spectrum. The wavelength of light emitted when an atom absorbs and releases energy can be used to identify the chemical composition of that substance.
