The total energy of an electron in an atom in an orbit is −3.4 eV-3.4 \text{ eV}−3.4 eV. Its kinetic and potential energies are, respectively:
−3.4 eV,−3.4 eV-3.4 \text{ eV}, -3.4 \text{ eV}−3.4 eV,−3.4 eV
−3.4 eV,−6.8 eV-3.4 \text{ eV}, -6.8 \text{ eV}−3.4 eV,−6.8 eV
3.4 eV,−6.8 eV3.4 \text{ eV}, -6.8 \text{ eV}3.4 eV,−6.8 eV

In Bohr's model of H atom, K.E.=∣TE∣=∣U∣2\text{K.E.} = |\text{TE}| = \frac{|\text{U}|}{2}K.E.=∣TE∣=2∣U∣. Therefore, K.E.=3.4 eV\text{K.E.} = 3.4 \text{ eV}K.E.=3.4 eV and U=−6.8 eV\text{U} = -6.8 \text{ eV}U=−6.8 eV.
