Why does fluorine have the highest en?
Fluorine is the most electronegative element because it has 5 electrons in it’s 2P shell. The optimal electron configuration of the 2P orbital contains 6 electrons, so since Fluorine is so close to ideal electron configuration, the electrons are held very tightly to the nucleus.
What is the electron affinity of Fluorine?
Electron affinity can be defined in two equivalent ways. First, as the energy that is released by adding an electron to an isolated gaseous atom….Elements.

Why is electron affinity highest in the top right corner?
We are looking at this in terms of across the period, not down a group. From left to right, the nuclear charge increases, resulting in a greater attraction to incoming electrons. So, we can say that from left to right across a period, the electron affinity increases upward.
Which element would have the highest electron affinity?
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.
What is electron affinity why the electron affinity of fluorine is less than that of chlorine?
Electron affinity of fluorine is less than that of chlorine. Due to the smaller size and thus, the greater electron-electron repulsions, fluorine will not accept an incoming electron with the same as chlorine.
Why does fluorine attract electrons?
Therefore, electrons from other atoms are more easily attracted. This is because Fluorine is more electronegative than Hydrogen and therefore pulls the electrons in the covalent bond closer towards it. This means that the Fluorine atom is slightly negative, while the Hydrogen atom is slightly positive.
What is the electron affinity of fluorine?
Fluorine DOES NOT have a law electron affinity, instead it has a HIGH electron affinity. The reaction F (g) + e- > F- (g) releases 79.5 Kcal/mole, the highest in the first row (Boron 7, Carbon 29, Oxygen 34, Fluorine 79.5). This means that after capturing one electron F (g)- is more stable than F (g).
Why is fluorine more reactive than chlorine?
Fluorine, though higher than chlorine in the periodic table, has a very small atomic size. This makes the fluoride anion so formed unstable (highly reactive) due to a very high charge/mass ratio. Also, fluorine has no d-orbitals, which limits its atomic size. As a result, fluorine has an electron affinity less than that of chlorine.
Why are the valence electrons in fluorine so high?
In a fluorine atom, the valence electrons are already packed pretty densely, and the energy from electrons repulsing each other (both electrostatically and because of Pauli exclusion principle) is comparatively high.
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.
