Atomic Structure Question 432
Question: What should be the kinetic energy and total energy of the electron present in hydrogen atom, if its potential energy is $ -5.02eV $ -
Options:
A) $ +2.51eV,-2.51eV $
B) $ +0.251eV,-0.251eV $
C) $ -2.51eV,-2.51eV $
D) $ +2.51eV,+2.51eV $
Show Answer
Answer:
Correct Answer: A
Solution:
- $ Total,energy=\frac{Potentialenergy}{2}=\frac{-5.02}{2} $ Total energy $ =-2.51eV $ Kinetic energy = - Total energy $ =-( -2.51eV )=+( 2.51eV ) $
