An electron is excited from n=1 ground state to n=3 state in an hydrogen atom. Which are true? Correct False?

Question

a)it takes more energy to ionize the electron from n=3 than from the ground state.
b)the electron is further from the nucleus on average in the n=3 state than n=1 state.
c)the wavelength of light emitted if the electron drops from n=3 to n=2 is shorter than that from n=3 to n=1
d) the wavelength emitted when electron returns to ground state from n=3 will be the same as wavelength of light absorbed to get from n=1 to n=3
e)for n=3, the electron is in the first excited state

Answer 1

a) False. Ground state ionization energy in H atom is highest -1313kj
b) Obviously, true.
c) Let's see.

2.39 X 10^15(1/2^2-1/3^2) = 3.319 X 10^14 Hz ( use this to divide speed of light)

2.998 X 10^8/3.319 X 10^14 = 9.03 X 10^-7m// 903nm

2.39 X 10^15(1/1^2-1/3^2) = 2.124 X 10^15

2.998 X 10^8/2.214 X 10^15 = 135nm So, n=3 to n=1 is shorter.

d)No, remember light is quantized.

e) You will have to answer this one yourself.

Answer 2

Ground State Of Hydrogen Atom

Answer 3

i do no longer remember if it grew to become into Bohr or no longer that did the Auf Bua concept yet i think of that could desire to be what you're conversing approximately. With the creation of quantum concept they think of that an electron could nicely be very almost everywhere at one factor in time - ex: it may desire to be here or it may desire to be on Mars. although, the two theories are correct interior the certainty they suspect that electrons have distinctive power tiers and that the valence electrons are the source of molecular bonding. IE: Carbon could have -4 can charge or a +4 can charge. Hydrogen has a +one million can charge jointly as Oxygen has a -2 can charge. Atoms seem chuffed while the outer power point is complete. for added information in this seek for suggestion from a periodic table.

Answer 4

F) doing your own homework is a good idea.
