Which has higher electron gain enthalpy O or F?

(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.

Which has more electron gain enthalpy N or C?

Nitrogen (1s22s22p3) has half-filled electronic configuration which is a stable configuration and hence it will have more electron gain enthalpy than B and C even though it lies to the right of carbon in the periodic table.

Which one has highest electron gain enthalpy?

Chlorine has the highest electron gain enthalpy. Although flourine is the most electronegative electron affinity of chlorine is higher as flourine due to its small size has a difficulty in accomodating an extra electron due to interelectronic repulsions.

Which has higher electron gain enthalpy N or O?

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

Which has more negative electron gain enthalpy Cl or F?

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.

Why is the electron gain enthalpy of 0 or F less than that of S or Cl?

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 does N have very low electron gain enthalpy?

As there are 7 electrons in its ground state. Electron gain enthalpy implies on adding an electron to it. But here there is half filled configuration for outermost orbit of Nitrogen so it would like to maintain its stability. Hope it helps!

Which of the following will have the most negative electron gain enthalpy PS Cl F?

Hence the element with most negative electron gain enthalpy is chlorine ; the one with the least negative electron gain enthalpy is phosphorus.

Which has higher electron affinity F or Cl?

Electron affinity of fluorine is less than that of chlorine. Since, energy released during the formation of Cl− (g) ion is more than that released in case of F−(g) ion, the electron affinity of chlorine is more than that of fluorine.

Why the electron gain enthalpy of F is less than Cl?

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.
