What is the significance of the terms "isolated gaseous atom" and "ground state" while defining the ionisation enthalpy and electron gain enthalpy?
Options
- AThese terms indicate that the enthalpy values are measured in a vacuum.
- BThese terms indicate that the enthalpy values are measured at standard temperature and pressure.
- C"Isolated gaseous atom" emphasises that the atom is in its most stable state, and "ground state" indicates tha
- D"Isolated gaseous atom" and "ground state" are technical terms without specific significance in the context of
Correct answer
C. "Isolated gaseous atom" emphasises that the atom is in its most stable state, and "ground state" indicates tha
Step-by-step solution
Correct Option is : (C) "Isolated gaseous atom" emphasises that the atom is in its most stable state, and "ground state" indicates that the electron configurations are in their lowest energy states.
