Electronegativity

Postby Alvaro Chumpitaz 4D » Tue Oct 29, 2019 7:21 pm

Okay I honestly do not remember what electronegativity is from high school, so what is it and if there is a trend on the periodic table for it?

Electronegativity is the ability of an atom to attract electrons to itself when it is part of a compound. I think electronegativity decreases down a group and increases across a period.

Electronegativity is the attraction for another electron. The closer you get to the noble gases, the more electronegative the element is. The trend is electronegativity increases as you move to the right of the periodic table and as you go up. F (upper right corner) is the most electronegative.

An easy way to remember the trends is electronegativity, ionization energy, and electron affinity all have the same periodic trend.

Electronegativity is how strongly an atom will attract electrons. Generally, as atoms get closer to having a full valence shell, they are more and more likely to gain an electron, which is why electronegativity increases as you go further right on the periodic table.

It is how strongly an atom will attract electrons. So as you go across the period increase and as you go down a group it decreases.

Electronegativity is the tendency of an atom to pull electrons. Electronegativity follows the same trends as ionization energy (Increases up and to the right).

Electronegativity is a characteristic of elements that defines how often these elements will try to gain more electrons from the bonding partner. (Whether it is covalent or ionic bond) It is important to also note that electronegativity increases as you go across and upwards. Consider it as like if the valence electrons are innermost and mostly filled, it is higher in electronegativity.

It is essentially how well an atom within a compound can attract electrons. Electronegativity decreases down groups, but increases going across periods.

Electronegativity increases from left to right and from bottom to top across the periodic table.

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. In the periodic table, it decreases down a group and increases across a period.

Electronegativity indicates how well an atom attracts electrons to itself. It increases across the period since atomic radius decreases across the period. With valence electrons being closer to the nucleus they experience more attraction forces. Therefore the atom attracts electrons better. Electronegativity decreases down a group because as going down the group atoms have more shells. Thus electrons are further away from the nucleus and experience less attraction force.
