300

The tallest peak or deepest valley in our light spectra indicates this.

What is the peak absorbance?

400

I am the wavelength ranges for UV, visible, IR, and Microwave radiation.

What is less than 400nm, 400-700nm, 700nm to 1 mm, and beyond 1 mm?

Two Atoms In A Molecule by Noah And The Whale

100

An IR spectrum tells me this about a molecule:

What are the types of bonds are present, which bonds are not present, and not how many are there?

200

How many lone pairs would you expect in C₁₂H₂₂O₁₁

What are 22 lone pairs?

300

I explain the common bonding pattern for C.

What is a 1s²2s²2p² electron configuration that indicates four vacancies in its outermost shell, thus meaning four electrons can delocalize and form four bonds naturally

400

I am the explanation as to why Nitrogen and Iodine would form NI₃ commonly.

What are 3 vacancies in N's valence shell allowing 3 electrons to delocalize to form bonds, and I having one vacancy.

500

I am why fluorine does not form more than one bond.

Why is costing energy to delocalize extra electrons?

What is one vacancy in the outermost shell?

I am how many energy peaks Xenon would generate on a PES.

What is 11?

400

The longer bond is weaker.

What is not necessarily true?

500

I am the three isomers of C₂H₂F₂
