Question

What is the value of ionization energy for a hydrogen atom?

Answer 1

Explanation:

13.6 electron volts

For a hydrogen atom, composed of an orbiting electron bound to a nucleus of one proton, an ionization energy of 2.18 × 10 −18 joule (13.6 electron volts) is required to force the electron from its lowest energy level entirely out of the atom.

Answer 2

Answer:

2.18 × 10power−18 joule
