What is the basic difference between the electron gain enthalpy and electropositivity? |
|
Answer» Solution :The amount of energy released when an electron is ADDED to a NEUTRAL gaseous isolated atom is called electron gain enthalpy. `X_(g) + e^(-) rarr X_(g)^(-) , Delta H = -ve` Electropositivity is the tendency to lose electron. It is directly related to the METALLIC character. More the ELECTROPOSITIVE character of an electron and thus the element is more metallic in nature. If electon gain enthalpy is more, the element has more tendency to gain electron. so that element will have non-metallic character. Elements having more electropositive character can act as strong reducing agents. while the elements having more electron gain enthalpies will act as OXIDISING character. |
