Why F has more electron gain enthalpy than O?
Why F has more electron gain enthalpy than 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.
Why the electron gain enthalpy of fluorine is less than of oxygen?
Fluorine atom is small in size and suffers with interelectronic repulsions between seven valence electrons. The added electron experiences much repulsion on smaller F. Hence its electron gain enthalpy is less.
Which has more electron gain enthalpy in oxygen?
The oxygen has higher electron gain enthalpy values and the Sulphur has negative values. Thus, the statement is true as Sulphur has more negative electron gain enthalpy than oxygen.
Which has more electron gain enthalpy fluorine or chlorine?
According to periodic properties, as we move down in a group of the periodic table the electron gain enthalpy should become less negative and fluorine is placed above chlorine yet has more negative electron gain enthalpy. Thus, the electron gain enthalpy of chlorine is more negative than that of fluorine.
Which of the following has more negative electron gain enthalpy oxygen or fluorine?
(i) O or F. 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.
Why fluorine has less electron gain enthalpy 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.
