Which one has high electron gain enthalpy?

Which one has high electron gain enthalpy?

Halogens have the highest electron gain enthalpy.

Which has highest electron gain enthalpy O or S?

S has high electron gain enthalpy because in oxygen there is more inter – electronic repulsion than sulphur on gaining electrons.

Which has more electron gain enthalpy O or CL?

CHLORINE HAS MORE NEGATIVE ELECTRON GAIN ENTHALPY.

Which has more electron gain enthalpy O or N?

Nitrogen has positive electron gain enthalpy whereas oxygen has negative. However, oxygen has lower ionization enthalpy than nitrogen.

Which has more electron gain enthalpy F or O?

Electron gain enthalpy of F is much more negative than that of O. This is because as we from O to F, the atomic size decreases and nuclear charge increases, thereby increase the attraction of the nucleus for the incoming electron and hence electron gain enthalpy becomes more negative.

Which among the following has highest electron gain enthalpy 1 he 2 NE 3 AR 4 XE?

Answer: Neon has the highest positive electrons gain enthalpy.

Which has more negative electron gain enthalpy C or Si?

b)Similarly,carbon has the most negative electron gain enthalpy as it will require an extra energy to add an electron & hence it will have maximum negative value of electron gain enthalpy.

Why is electron gain enthalpy of S more than O?

Oxygen does not have a d-orbital, but sulphur has a d-orbital. So, oxygen is not able to accommodate more electrons due to its small size showing more electron repulsion. Hence, Sulphur has more electron gain enthalpy than Oxygen.

Which has higher electron gain enthalpy fluorine or chlorine and why?

Among the 4 halogen atoms mentioned above, the atom element which will have a greater value of electron gain enthalpy will be chlorine. 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 lesser electron gain enthalpy N or O?

Nitrogen has positive electron gain enthalpy whereas oxygen has negative. However, oxygen has lower ionisation enthalpy than nitrogen.

Why is electron gain enthalpy of O?

The electron gain enthalpy of O and F less than that of S or Cl is due to small size of O/F the inter electronic repulsion in compact 2p-orbital is much more than the repulsion in 3p-orbital of S/Cl hence, the incoming new electron feels less attraction in O/F and more attraction in S/Cl.

Which has more negative electron gain enthalpy O or S?

Oxygen is more electronegative and has more density compared to sulphur. Thus, sulphur has more negative electron gain enthalpy.

What is the exception in electron gain enthalpy?

Exception in Electron Gain Enthalpy: In the case of Chlorine and Fluorine, Chlorine has a higher negative electron gain enthalpy value. In between Sulphur and Oxygen, Sulphur has a higher negative value than oxygen.

Why does chlorine have the highest electron gain enthalpy?

Normally electron affinity decreases as we move down the group. However, fluorine has a lower value than chlorine which is due to its small size. Hence, chlorine has the highest electron gain enthalpy. Was this answer helpful?

Why does sulphur have high electron gain enthalpy?

S has high electron gain enthalpy because in sulphur there is more inter-electronic repulsion than oxygen, therefore, more energy is released in case of sulphur on gaining electrons. Was this answer helpful?

Which halogen has the highest electron affinity?

Chlorine Halogens have the highest electron gain enthalpy (electron affinity). Normally electron affinity decreases as we move down the group. However, fluorine has a lower value than chlorine which is due to its small size.
