Minimum Energy to Free an Electron from Hydrogen Atom

Hydrogen atom consists of only one proton and one electron. The minimum energy required to free an electron from the hydrogen atom's ground state is known as the ionization energy.

Options:
- A) 13.6 eV
- B) -13.6 eV
- C) 10.2 eV
- D) 6.8 eV

Correct Answer:
- A) 13.6 eV

Explanation:
- The ionization energy of hydrogen atom is 13.6 eV, which is the energy required to remove the electron from the ground state to infinity.
- This energy is a positive value because work must be done on the system to remove the electron against the attractive force of the nucleus.
- The negative sign would indicate that the electron is bound to the nucleus with less energy than in the free state, which is not the case for the hydrogen atom.
