Question

PLEASE LET ME KNOW WHICH NUMBER YOU ARE ANSWERING! I am so lost on these and we havent even gone over it in class.

1.) Certain predictions of Maxwell's classical theories of electromagnetism did notfit the experimental data. Describe the data and the problems they caused, and explain how they were accounted for using Planck's concept of quantisation of energy and how this solved these problems.

2.)How are atomic line spectra explained based on Planck's ideas?

3.)How do these ideas relate to the Bohr model of the atom?

5.) For transition of an electron from energy level n=4, to energy level n=1 of the hydrogen atom:

a.)Will energy be emitted or absorbed? Explain your answer.

b.)What is the value of this energy expressed in KJ/mol.

6.) What is the wavelength of the light that corresponds to this transition, expressed in metres?

Explanation / Answer

bohr's model predicted that elctrons orbit nucleus in orbits with fixed energy and thus fixed angular momentum . this implies they can not remain in an inbetween state and must occupy on e orbit or the other . as the transition takes place between finite states , the energy releasesd thus is in dicrete packets(according to plank's theory) which produces fine line sin the spectrum.
