electronegativity

Postby Clarissa Nava 3H » Sat Dec 08, 2018 7:18 pm

does this have to doe with electron charges or the energy release when an electron is added to an atom?

Electronegativity is the tendency of an atom to attract a shared pair of electrons towards itself. It increases across and decreases down the periodic table.

Electronegativity is related to the electron-pulling ability of an atom. Elements at the top right corner of the periodic table have the highest electronegativity, meaning that electronegativity increases as you move right across the table and decreases as you move down.

Not necessarily; electronegativity refers to the strength of the "pull" an element has on electrons; the more full the valence shell of the element is, the less electronegative it is.

In terms of periodic trends, uhedlund described it pretty well. Just to be more specific, the trend displays that electronegativity increases from the bottom left corner of the periodic table to the upper right hand corner. This means that elements like Fluorine and Chlorine have an extremely high electronegativity, while elements (mostly metals) from the opposite side of the periodic table tend to display a smaller electronegativity. Hope this helps!

I remember electronegativity as an atom's "resistance" to release an electron hence F being the most electronegative atom as it has a high number of valence electrons requiring a higher amount of energy to excite a single one.

Electronegativity is the strength atoms have in puling other electrons to complete their valence shell

I think you may be thinking of electron affinity, which refers to the amount of energy released when an electron is added to a neutral atom. Same trend, but not interchangeable.

Electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons toward itself. Electronegativities generally increase from left to right across a period and generally decrease from top to bottom within a group.

I have been looking for an answer to this question and yours makes perfect sense! Thanks so much!!

It can also be added that electronegativity has an inverse relationship with atomic radius, therefore has an opposite periodic trend. This is because a larger atomic radius usually means more shielding experienced by the nucleus, giving it less affinity for attracting electrons from other atoms.
