Question

An electron is excited from the ground state to the n = 3 state in a hydrogen atom, which of the following statements are true? correct any false statement. (a) It takes more energy to ionize (remove) the electron from n3 than from the ground state O True O False It takes |--Select energy to ionize an electron from n = 3 than from the ground state (b) The electron is farther from the nucleus on average in the n3 state than in the ground state O True O False The electron is-Select- the nucleus on average in the n = 3 state than in the ground state. (c) The wavelength of light emitted if the electron drops from n = 3 to n = 2 is shorter than the wavelength of light emitted if the electron falls from n = 3 to n = 1 O True False The wavelength of light emitted if the electron drops from n = 3 to n 2 is Select-' than the wavelength of light emitted if the electron falls from n 3 to n = 1 (d) The wavelength of light emitted when the electron returns to the ground state from n = 3 is the same as the wavelength of light absorbed to go from n = 1 to n = 3 O True O False The wavelength of light emitted when the electron returns to the ground state from n = 3 is-Select- the wavelength of light absorbed to go from n-1 to n-3 (e) The first excited state corresponds to n = 3 True False The first excited state corresponds to n = ??? .

Explanation / Answer

Answer:

a)))False.

At n=3 the electron has a higher amount of energy than n=1, and so only requires a smaller amount to reach ionization.
it takes more energy to ionize (completely remove) the electron from n=3 than from the ground state"

b)))True

the electron is farther from the nucleus on average in the n=3 state then in the n=1 state"

c)))False.

The difference in energy between 3 and 2 is smaller than the energy difference between 3 and 1. The higher the energy, the higher the frequency, and thus the shorter the wavelength.

the wavelength of light emitted if the electron drops from n=3 to n=2 will be shorter than the wavelength of light emitted if the electrons fall from n=3 to n=1"

d)) True.

the wavelength of light emitted when the electron returns to ground state from n=3 will be the same as the wavelength of light absorbed to go from n=1 to n=3"

e)))))False.

n=2 is the first excited state, while n=1 is the ground state.

for n=3, th electronis in the first excited state."
