What evidence leads us to believe that energy levels in the hydrogen atom are quantities?

Because only certain photons are emitted, we know that only certain energy changes are occurring. This means that the hydrogen atom must have certain discrete energy levels. Excited hydrogen atoms always emit photons with the same discrete colors (wavelengths). They never emit photons with energies between those shown. So we concluded, all hydrogen atoms have the same set of discrete energy levels.

Explanation:

unit 4 test (i have all the answers if you want me to send the link i can)

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
