Q
Q: What is the energy of the ground state of a hydrogen atom?
Solution:
The energy of the ground state of a hydrogen atom is -13.6 eV.
Steps: 5
Show Steps
Step 1: Understand what a hydrogen atom is. A hydrogen atom consists of one proton and one electron.
Step 2: Learn about energy levels in atoms. Electrons can exist in different energy levels, with the lowest energy level called the ground state.
Step 3: Know that the ground state of a hydrogen atom is the most stable state for the electron, where it has the least energy.
Step 4: Find out the value of the energy in the ground state. For hydrogen, this value is -13.6 electron volts (eV).
Step 5: Understand that the negative sign indicates that the electron is bound to the nucleus and energy must be added to free it.
