You will have to look up the Pauling scale yourself, but the O atom, first row, and rightmost on the table, will be most electronegative , followed by nitrogen and bromine.
Which element is more electronegative than oxygen?
And thus across a Period (from RIGHT to LEFT as we face the Table), fluorine is more electronegative than oxygen , which is more electronegative than nitrogen , which is more electronegative than carbon , which is more electronegative than boron . Can you see the Periodic trend?
Does bromine have high electronegativity?
The first scale of electronegativity was developed by Linus Pauling and on his scale bromine has a value of 2.96 on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine).
Is oxygen more electronegative than halogens?
Moreover, atomic radius decreases across the period because of increasing nuclear charge. Hence, fluorine is the most electronegative , followed by oxygen. Other halogens are simply too large to match oxygen’s electronegativity.
Which is more electronegative oxygen or bromine?
| Element Electronegativity (Pauling) | O 3.4 [3.44] | Cl 3.2 [3.16] | N 3.0 [3.04] | Br 3.0 [2.96] |
|---|
Is C or O more electronegative?
| 3A | B 2.04 | 4A | C 2.55 | 5A | N 3.04 | 6A | O 3.44 | 7A | F 3.98 |

Why oxygen is the most electronegative?
Why is oxygen more electronegative than nitrogen? Oxygen has 8 protons in the nucleus while nitrogen only has 7. A bonding pair will experience more attraction from the oxygen’s nucleus than from nitrogen’s, and so the electronegativity of oxygen is greater.
Why is bromine so electronegative?
S has less shells compared to Se and hence the pull experienced by the electrons due to the nucleus is less. But in Se, there are more shells, more electrons and greater pull is experienced , thus increasing its electronegativity.
Is BR a bromine?
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour.
What is the highest electronegativity value?
The electronegativity scale was developed by Nobel Prize winning American chemist Linus Pauling. The largest electronegativity ( 3.98 ) is assigned to fluorine and all other electronegativities measurements are on a relative scale.
Is oxygen electronegative or electropositive?
Cesium and francium are the highest electropositive elements in the entire periodic table. Whereas, fluorine, chlorine, and oxygen are the most electronegative elements in the periodic table which also means that they are the least electropositive elements in the periodic table.
Why is Cl more electronegative than C?
| carbon 2.5 | chlorine 3.0 |
|---|
Is oxygen or hydrogen more electronegative?
Thus oxygen has a higher electronegativity than hydrogen and the shared electrons spend more time in the vicinity of the oxygen nucleus than they do near the nucleus of the hydrogen atoms, giving the atoms of oxygen and hydrogen slightly negative and positive charges, respectively.
Is oxygen more electronegative than iodine?
The trend is for electronegativity to increase going across and up the periodic table. Advanced: ... Oxygen is more electronegative (likes electrons more) than carbon. Chlorine is more electronegative than iodine.
Which is more electronegative O or I?
This table is the Pauling electronegativity scale. ... Because fluorine is the most electronegative element, the electrons tend to “hang out” more toward the fluorine atom when fluorine is covalently bonded to other atoms. Oxygen is the 2nd most electronegative element .
