Question # 1

What is meant by line spectrum? How line spectrum can be used for the identification of elements?

  • Ans 1: When an electron jumps from higher energy state to lower energy state than emits energy and make a spectral line.
    E2- E1=hf
    This is called line spectrum.And different elements emit line spectrum of different wavelengths,So they can be identifiedeasily.

Question # 1

Can the electron in the ground state of hydrogen atom absorb a photon of energy 13.6 eV greater than 13.6 eV?

  • Ans 1: Yes an electron in the ground state of hydrogen atom can absorb a photon of energy 13.6 eV and greater than 13.6 eV.
    ionization energy of hydrogen atom in ground state is 13.6 eV.So if hydrogen absorb a photon of energy greater than 13.6 eV than the surplus energy of photon appear as K.E of electron
