3 (b) The energy of a Bohr atom in the n-th excited state is given by the formula E--a2mc2 2,7, where α-e2/(4πέρ,10hc)-1 /137, m is the electron mass and e denotes the electron electric charge. i) Why is the total energy negative? Explain briefly your answer. ii) What is the radius of the electron in the n-th excited state in the Bohr atom? To answer that correctly follow the next steps Use Bohr's angular momentum quantization principle to obtain an...
1. We can observe the wavelengths emitted from Hydrogen. When Hydrogen electrons transition between states, they absorb or emit a particle of light called a photon with energy E=hf. Here f is the frequency of light and h is a constant. a. How much energy does an electron in the n=1 (lowest-energy) state of Hydrogen have? Repeat for n=2 and n=3. b. How much energy is emitted if an electron in the n=3 state transitions to the n=2 state? c....
even though the solutions are literally there i am confused
and do not know how to do any of these problems

Question #4: (25 points total) In this problem, you are going to walk you through a brief history of quantum mechanics apply the principles of quantum mechanics to a physical system (free electron) 1900 Planck's quantization of light: light with frequency v is emitted in multiples of E hv where h 6.63x10-341.s (Planck's constant), and h =hw h 1905 Einstein postulated that the quantization of light corresponded to particles, now called photons. This was the...
Can you please explain how to get the answers? I don't
understand any of the drawings or the theory. Please explain in
detail
1. Using Frontier Molecular Orbital (FMO) theory which molecular orbital below best represents the HOMO of butadiene (circle it)? Which molecular orbital below best represents the LUMO (identify it with a rectangle)?
Q2: At the top are the 3 wavelengths we found. How do you find
which energy levels it transitions between? (ignore most of my
work)
Graded activity: The wavelengths to the side are what we
found. We are also given energy level diagrams for each element. We
believe it’s hydrogen but what work would we do to find this?

can you explaination for thes questions how did we got these
right answers. Thankyou!
