Electronegativity is a measure of how strongly an atom – in a molecule – is able to lure electrons in a bond come itself.
You are watching: Is nitrogen more electronegative than oxygen
Factors affecting electronegativity:
1) The atom number
The atom number is the variety of protons in the cell nucleus of one atom.It determines the chemistry properties of an element and also its location in the routine table.The greater the atomic number, the more powerful the electronegativity.
2) The atomic radius
The atomic radius the a chemical element is generally measured through the street from the center of the nucleus to the border of the outermost great of electrons.The enlarge the atomic radii, the weaker the electronegativity.

What is electronegativity measure in?
The most usual measurement for electronegativity is the Pauling scale, design by two-time Nobel prize winner Linus Pauling. Electronegativity scale for aspects tell how solid each facet (relative to every other) can lure the bonding electron to itself. The higher the electronegativity number, the an ext the atom will attempt to pull electrons to itself.
Why is oxygen much more electronegative 보다 nitrogen?
Oxygen is higher in atom numberOxygen has actually 8 protons in the nucleus whereas nitrogen only has actually 7.A bonding pair of electrons will certainly experience much more attraction native the oxygen’s nucleus the from nitrogen’s, for this reason the electronegativity of oxygen is greater.
Why is sulphur less electronegative than oxygen?
Reasons why oxygen is much more electronegative than sulfur:Oxygen has 2 energy levels, sulfur has 3The bonding electron in sulfur are more away indigenous the cell core of the atomWhen bonding electron are further from the cell core of the atom, over there is much less attraction indigenous the nucleusthe bonding pair of electron in oxygen will certainly experience an ext attraction native its nucleus than sulfur’s bonding electronsHence oxygen is a much more electronegative atom

The smaller sized atom has actually a higher electronegativity
Electronegativity trends present in the routine table
When girlfriend move across the regular table, the number of protons in the nucleus increases (with no boost in power level), thus the electronegativity increases.

When the atomic number increases under a group, there is additionally an increase in power levels. The atomic radius is greater as such electronegativity decreases.
