Trend of Electronegativity

Postby 205389184 » Mon Nov 04, 2019 1:02 am

In what way should we describe the trends of electronegativity?

Electronegativity increases up the periodic table and towards the right. Fluorine is the most electronegative element.

Electronegativity is the electron pulling power of an atom. As you move to the right of the periodic table, the electronegativity increases because atoms get closer and closer to having a full octet. As you move up the periodic table, electronegativity also increases because there is less shielding from other orbitals. Therefore, the atom has a greater ability to pull electrons.

That means the electronegativity is related to the radius right? Since the upper right corner of the table has a stronger pull on an electron, it should make their size smaller correct?

Electronegativity increases from left to right and up the periodic table.

Electronegativity increases across the period and decreases down the group.

I think of the trend going in a diagonal arrow up to the upper right side. Toward Flourine.

the trend for electronegativity is that it increasing going right and up periods

The trend for electronegativity is the same for the trend in atomic spectra and ionization energy with some exceptions. It increases from right to left and decreases from up to down a group.

Electronegativity increases as you move up and to the right of the periodic table, which makes Fluorine the most electronegative

Electronegativity is larger when you move close to upper right corner of the periodic table (F is the largest).

Electronegativity decreases as you move down a group and increases as you move across a period. It increases as you move across a period because the nuclear charge increases as you move right. It decreases as you move down a group because the electrons are increasingly experiencing weaker attraction from the nucleus.

Does ionization have the same trend?

Ionization does have the same trend; it increases going across the periodic table and decreases going down.

Electronegativity increases in an overall diagonal line starting with Francium as the least electronegative and Fluorine as the most electronegative. This occurs because as you move up a period, the number of valence shells decreases meaning the atom is getting smaller which in turn means the protons are pulling on electrons more tightly and thus are better able to attract any extra electrons needed to fill its last valence shell. Electronegativity also increases across a period for the same reason, more protons in the nucleus means a stronger pull for electrons.

Ionization energy has the exact same trend. Ionization energy and electronegativity go hand in hand, the more electronegative an atom is the more it wants an electron and thus the more tightly it will hold on to its own electrons. Across a period, atoms gain protons and thus are able to hold on more tightly to the surrounding electrons and the harder it is to pull electrons from an atom. Going up a period, the atoms lose a valence shell and again the protons pull more tightly on the valence electrons thus making it more difficult to steal an electron away which then increases the ionization energy.

ionization energy and electronegativity follow the same trend. Going down the periodic table they decrease and going right, they increase.
this makes fluorine the most electronegative atom.
cesium has the lowest ionization energy.

On the periodic table electronegativity increases from left to right and decreases from top to bottom.

Fluorine is the most electronegative element. Electronegativity decrease down a column and across a row (right to left). Or oppositely it increases up a column and left to right across a row.

electronegativity describes the pulling power of the atom. Generally, across a period, electronegativity will increase. Down a group, it will decrease. This is due to effective nuclear charge and size of the atom. The smaller the atom, the closer to the nucleus the electrons can get, meaning that they will be pulled on more tightly. The larger, the less the electrons will feel the pull, meaning the electronegativity of that atom is less.

Electronegativities generally increase from left to right across a period. This is due to an increase in nuclear charge. Electronegativities generally decrease from top to bottom within a group due to the larger atomic size.

Electronegativity increases to the right and up the periodic table because the effective nuclear charges increase.
