Structure of Atom Test - 2

x-rays is the correct answer.

The wavelength and frequency are inversely related to each other, thus the radiation with the highest frequency will have the shortest wavelength.

The wavelength may be arranged as, X-ray < ultraviolet < Infra red < microwave.

Max Planck gave the Planck's quantum theory and was the first to determine the value of h which is the Planck's constant.

Hint:         l =   0,     1,      2,    3

Orbitals        s      p      d      f

l = 2 corresponds to d orbitals which can take upto 10 electrons.

For n=2 , l has only two possible values 0 and 1 and possible values of m are 0 and -1,0 and +1.

The Thomson's pudding model explained that atoms were spheres of positive charge with electrons embedded in it.

Third shell does not have f subshells.

The sum of value of Principal quantum number (n) and Azimuthal quantum number (l) determines the energy of an electron in an orbital.

Energy of 1^st Bohr Orbit of hydrogen is -13.6 eV.

For given n,  the possible l values are 0, 1, and 2.

For l =0, possible m_l values is 0. 

For l =1, possible m_l values are: +1,0, -1.

For l =2, possible m_l values are: +2,+1,0, -1,-2

There are two possible m_s values for each m_l value: +1/2 or -1/2

Spin quantum number indicates the two possible states of an electron within an orbital with same value of other quantum number, their Values are + 1/2 or –1/2
