Differbetween
Answer. Answer: Electronegativity is defined as the tendency of an atom to attract a shared pair of electron towards itself in a covalent bond . While electron gain enthalpy is the amount of energy released when a gaseous neutral atom accepts an extra electron.

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. |
What is the difference between electron gain enthalpy and electronegativity explain with example?
Electron gain enthalpy is the tendency of an isolated gaseous atom to accept an additional electron to form a negative ion. Electronegativity is the tendency of the atom of an element in a chemical compound to attract a shared pair of electrons towards it in a covalent bond.
What is the difference between electron gain enthalpy and electron affinity?
These two terms are same, they have only the difference in sign. 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.
What is electron gain enthalpy with example?
Hence, the second electron gain enthalpy of an element is positive. Example: When an electron is added to sulphur atom to form S– ion, it releases energy whereas energy is required when another electron is added to S– ion to form S2- ion.
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 basic difference between electron gain enthalpy?
What is the basic difference between the terms electron gain enthalpy and electronegativity?
| Electron gain enthalpy | Electronegativity |
|---|---|
| It is the tendency of an atom to attract outside electrons | It is the tendency of an atom to attract shared pair of electrons |
Would you expect the second electron gain enthalpy of O as positive?
When an electron is added to O atom to form O– ion, energy is released. Thus, the first electron gain enthalpy of O is negative. ... Thus, the second electron gain enthalpy of O is positive.
What is electron gain enthalpy?
Electron gain enthalpy is defined as the amount of energy released when an electron is added to an isolated gaseous atom. During the addition of an electron, energy can either be released or absorbed. ... Hence, the nuclear force applied on the electrons in the case of Sodium will be less.
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 element has highest electron gain enthalpy?
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.
Which has more electron gain enthalpy?
Chlorine has the highest electron gain enthalpy in the periodic table .
