. The ground state energy of hydrogen atom


 is -13.6 eV. What are the kinetic and
potential energies of the electron in this state?
Answer
Ground state energy of hydrogen atom, E = - 13.6 eV
This is the total energy of a hydrogen atom. Kinetic energy is equal to the negative of
the total energy.
Kinetic energy = - E= - (- 13.6) = 13.6 eV
Potential energy is equal to the negative of two times of kinetic energy.
Potential energy = - 2 x (13.6) = - 27.2 eV

 

Best Answer

Explanation:

Ground state energy of hydrogen atom is E=−13.67eV 

The kinetic energy of the electron is given as: KE=−E =+13.67eV 

The potential energy of the electron is given as: PE=−2×KE =−27.2eV

Final Answer:

Hence,

The kinetic energy of the electron is +13.67eV 

The potential energy of the electron is −27.2eV
