Differbetween
Electron gain enthalpy is the energy released when we add one more extra electron to isolated neutral atom while electron affinity is the tendency of isolated atom to gain 1 more electron in it.

Is electron affinity negative of electron gain enthalpy?
Electron affinity means love for electron. It is the negative of the electron gain enthalpy.
What is the main difference between electron gain enthalpy and electronegativity?
| Electron gain enthalpy | Electronegativity |
|---|---|
| i) It is the property of an isolated atom of an element in gaseous state. | i) It is the property of an atom of the element when it is bound to some other atom. |
| ii) Its value can be determined experimentally. | ii) The value of electronegativity can not be determined experimentally. |
Which has highest electron gain enthalpy or electron affinity?
But, chlorine is large in size and has comparatively low value of electronegativity than fluorine. Thus, it accepts an electron easily and has the highest electron gain enthalpy value. Thus, the correct option is B.
What is electron gain affinity?
Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.
Which has highest electron affinity?
Halogens has higher electron affinity and it is supposed to be for fluorine, but chlorine has higher electron affinity than fluorine due to fluorine's smaller size. Hence, among given options chlorine has highest electron affinity.
Which has more electron gain enthalpy?
Chlorine has the highest electron gain enthalpy in the periodic table .
Why is the second electron gain enthalpy of oxygen positive?
When an electron is added to an isolated oxygen atom, it becomes uninegative ion. Now if one more electron has to be added, then it will experience a repulsive force or columbic force of repulsion. ... Therefore , the second electron gain enthalpy is positive for oxygen.
Why electron gain enthalpy of fluorine is less than chlorine?
The negative electron gain enthalpy of fluorine is less than that of chlorine. It is due to small size of fluorine atom. As a result, there are strong interelectronic repulsions in the relatively small 2p orbitals of fluorine and thus, the incoming electron does not experience much attraction.
What is the difference between electronegativity and electron affinity?
Electronegativity is defined as a chemical property which decides the propensity of an atom to attract an electron. ... Electron affinity is defined as the amount of energy liberated when a molecule or neutral atom acquires an electron from outside.
Which halogen has highest electron affinity?
Therefore, chlorine has a higher electron affinity than fluorine, and this orbital structure causes it to have the highest electron affinity of all of the elements.
Why electron gain enthalpy of MG is positive?
Solution : They have fully filled s- orbitals and hence have no tendency to accept an additional electron. That is why electron gain enthalpies Be and Mg are positive. ...
Which element has second highest electron gain enthalpy?
As we know that elctron gain enthalpy increases across period and decreases along group. Hence halogen has highest electron gain enthalpy. Among halogen fluorine has lower electron gain enthalpy than chlorine due to small size.
