Why does fluorine have a higher electron affinity than oxygen?

This also explains why fluorine has a larger electron affinity than oxygen, as the electron brought in from the environment is being added to the 2pz orbital of fluorine which is closer to the nucleus (than the outer orbital of an oxygen atom) at a lower energy level where it becomes the outermost electron of the F- …

Which element has the highest electron affinity for electrons?

Chlorine
Chlorine has the highest electron affinity among the elements. Its high affinity can be attributed to its large atomic radius, or size. Because chlorine’s outermost orbital is 3p, its electrons have a large amount of space to share with an incoming electron.

Which element has highest electron affinity in oxygen family?

But due to the smallest size of the oxygen atoms among the group there is a huge repulsion to the incoming electron due to the small size. So, on the basis of size, electron affinity of selenium must be highest.

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.

Which has higher electron affinity f or ne?

fluorine has more affinity becoz it is reactive but neon is stable.

Which has highest electron affinity fluorine or neon?

In the modern periodic table, electron affinity increases on moving left to right in a period while it decreases on moving down the group. Thus, noble gases have the least electron affinity in a period. Hence, we can conclude that in a period, fluorine (halogen) has higher electron affinity than neon (noble gas).

This also explains why fluorine has a larger electron affinity than oxygen, as the electron brought in from the environment is being added to the 2pz orbital of fluorine which is closer to the nucleus (than the outer orbital of an oxygen atom) at a lower energy level where it becomes the outermost electron of the F- anion.

What is the electron affinity of argon?

It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine. Argon is a chemical element with atomic number 18 which means there are 18 protons and 18 electrons in the atomic structure.

Which of the following elements has the most electrons affinity?

Florine has the most electrons affinity than Oxygen as Oxygen is group 6 element which has 1 less proton in the nucleus than Florine in group 7 elements. The number of nucleus is less in group 6 than in group 7.

What is the atomic number of oxygen and fluorine?

By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. Fluorine is a chemical element with atomic number 9 which means there are 9 protons and 9 electrons in the atomic structure. The chemical symbol for Fluorine is F.
