Question

What is electronegativity? Identify the most and least electrone groups of elements in the periodic table. Why is fluorine special in terms of electronegative
​

Answer 1

Answer:

Electronegativity is a measure of an atom's ability to attract shared electrons to itself

Alkali metals have the lowest electronegativities

Explanation:

Why does fluorine have the highest electronegativity of all the elements?

Electronegativity is defined as the property which describes the tendency of an atom to attract electrons towards itself.

It depends upon the atomic number but more importantly on the distance at which electrons reside.

Fluorine, compared to other elements is more Electronegative because it requires only one electron to complete an octate and attain stability, and the distance at which valence electrons reside is the minimum as compared with other elements having 7 electrons in the outermost or...

Which element has the highest electronegativity? Why?

If fluorine has the highest electronegativity, then why doesn’t it have the highest electron affinity?

Why is fluorine's electronegativity greater than neon's? They both have same number of shells, but neon has 1 proton and 1 electron more than fluorine, meaning that its attraction of the nucleus for the valence electrons should be greater.

What is the electronegativity of d-block elements?

Why is the electronegativity of fluorine high?

Stock answer is, all halogens are general assholes. They gave 7 electrons on their outermost (valence) shell. This, for some reason, makes them very eager to get 8.

Fluorine is the smallest of halogens. This mean there are fewer layers of electrons between fluorine’s valence shell and nucleus. With few electrons to shield the nucleus, the pull of the nucleus at the valence shell is extra strong. Fluorine is the king asshole. Chlorine is the next baddest halogen, but it is larger and there are a lot more electrons in between the nucleus and the valence shell.

The long answer would be; why would having 7 electrons in valence shell make you an asshole? That answer would be quite long, and most people would be surprised that you ask such weird questions. So stick to the dogma: You need 8 electrons in valence shell to become stable.
