The calculated electron gain enthalpy values for alkaline earth metals and noble gases are positive. How can you explain this? |
|
Answer» 1. Generally alkaline earth metals having one, two or three valence electrons prefer to lose electrons in order to get inert gas configuration. So it is difficult to add electron to alkaline earth metals. So they have positive electron gain enthalpy values. 2. Noble gases are stable. So they do not prefer to take electrons. So they have positive electron gain enthalpy. |
