Does lithium or oxygen have greater electronegativity?
Electronegativity (Pauling scale)
| 1 | 16 | |
|---|---|---|

| 1 | H 2.20 | |
| 2 | Li 0.98 | O 3.44 |
| 3 | Na 0.93 | S 2.58 |
Why is oxygen 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 lithium more electronegative?
From the above question we can say that electronegativity of an element is its tendency to attract bond pair electrons. Li has 1 electron in its valence shell (n=2). The valence shell of Li is closer than that of Mg which makes Li more electronegative than Mg.

Why does the electronegativity decrease down a group?
Going down a group, the electronegativity of atoms decreases. As you move down a group in the periodic table, atoms increase in size, with a greater number of energy levels. The extra energy levels and increased covalent radius keep the bonding electrons further away from the nucleus.
Is lithium an electronegativity?
0.98
Lithium/Electronegativity
Why is oxygen more electronegative than chlorine?
We confirm this by looking at the atomic radius of oxygen and chlorine, seeing that oxygen is a smaller atom than chlorine, and thus that the force felt by the outermost electrons to the nucleus pull oxygen’s electrons more chlosely than chlorine’s.
Why is oxygen more electronegative than hydrogen?
Oxygen is more electronegative because of a larger positive charge in the nucleus with very little electron shielding effects. More electrons would repel electrons, and more protons will attract electrons. This is the way.
What is the electronegativity of oxygen?
3.44
Oxygen/Electronegativity
Examining the table above, we see that O has an electronegativity of 3.44, and H has an electronegativity of 2.20. Based on the concept of electronegativity as we now understand it, we can surmise that the oxygen (O) atom will tend to “pull” the electrons away from the hydrogen (H) when they are interacting.
Why is lithium atom smaller than sodium atom?
Li has 2 shells and Na has 3 shells. So Li is smaller than Na. This is due the fact that lithium has two orbitals while sodium has four orbitals . Hence size of Na atom is bigger than that of Li .
Why does electronegativity increase from lithium to fluorine?
electrons. (ii) Justify the trend in electronegativity of the elements from lithium to fluorine. There is an increase in the number of protons and thus the nuclear charge / attractive force of the nucleus. As the electrons are added to the same energy level, there is no increase in repulsion between energy levels.
Why is electronegativity higher at the top of a group?
This is because as you go from top to bottom down a group, the atoms of each element have an increasing number of energy levels. Atoms with high ionization energies have high electronegativities because the nucleus has a strong attraction for electrons.
