The total energy of an electron in an atom in an orbit is –3.4 eV. Its kinetic and potential energies are, respectively.
  1. A
    3.4 eV, – 6.8 eV
  2. B
    3.4 eV, 3.4 eV
  3. C
    – 3.4 eV, – 3.4 eV
  4. D

Correct answer: A

Apply Bohr's Atomic model for H-atom

KE = –T.E and PE = 2T.E

Given, T.E = –3.4 eV

∴\therefore∴ KE = +3.4 eV and PE = -6.8 eV
