Nettetii) Electronegative of the element decreases down the group and increases across the period. iii) Atomic size increases down the group and decreases across a period (left to right). iv) Metallic character increases down the group and decreases across a period. On the basis of above trends of the Periodic Table,asnwer the following about the ... NettetAnswer (1 of 3): Electron gain enthalpy of phosphorus is more negative than nitrogen because in case of nitrogen while adding one electron in nitrogen electron electron repulsion is high due to small size of nitrogen but in case of phosphorus this electron electron repulsion is less compared to p...
Nettet10. apr. 2024 · Electron gain enthalpy is defined as the energy released when an isolated gaseous atom accepts the electron to convert into an anion. Now, whenever the energy is released from the system to the surroundings, it is taken to be negative (as per thermodynamics) and positive when the system absorbs energy; thus, electrons gain …
NettetSolution. (a) Electron gain enthalpy depends on the size of an atom. Smaller the size, more negative would be the electron gain enthalpy. F is a smaller size than O, thus electron gain enthalpy of F is more negative than O. (b) Cl is larger in size as compared to F, still electron gain enthalpy of Cl is more negative than F, this is due to the ... The electron affinity of molecules is a complicated function of their electronic structure. For instance the electron affinity for benzene is negative, as is that of naphthalene, while those of anthracene, phenanthrene and pyrene are positive. In silico experiments show that the electron affinity of hexacyanobenzene surpasses that of fullerene.

The reason for the deviation is due to the smaller size off. Due to its small size, the electron repulsion in the relatively compact 2p-subshell are comparatively large and hence the attraction for incoming electron is less … proact filtrationNettet6. apr. 2024 · Hence, the electron gain enthalpies of chalcogens tend to decrease while progressing down the group. However, oxygen has a lesser negative electron gain enthalpy than sulfur, which is explained by the compressed atomic structure that oxygen has, which tends to contribute to the interelectronic repulsion that occurs between the … proact finland oyNettetElectron gain enthalpy.
