Which has more electron affinity nitrogen or oxygen?

Answer: Oxygen has more electron affinity because Nitrogen gains more stability by attaining partial configuration.

What is the electron affinity for oxygen?

Electron affinity can be defined in two equivalent ways. First, as the energy that is released by adding an electron to an isolated gaseous atom….Elements.

Z 8
Element 16O
Name Oxygen
Electron affinity (eV) 1.461 113 6(9)
Electron affinity (kJ/mol) 140.976 0(2)

Why is the electron affinity of nitrogen significantly lower than oxygen?

since nitrogen has half filled p orbital in its valence shell so it does not tend to accept another electron as half filled configuration is more stable . but in order to add one more electron energy has to be supplied and thus it’s E. A. is lower than C and O.

Why is ionization energy of oxygen less than that of nitrogen?

Oxygen also has an unexpectedly low ionisation energy, less than that of nitrogen. This is due to an electron being added to an already half full orbital in oxygen, which results in electron electron repulsion, which will lower the ionisation energy.

Which has maximum electron affinity?

Chlorine has the highest electron affinity among the elements. Its high electron affinity can be attributed to its large atomic radius, or size. Because chlorine’s outermost orbital is 3p, its electrons have a large amount of space to share with an incoming electron.

Which has the highest electron affinity?

Therefore, chlorine has a higher electron affinity than fluorine, and this orbital structure causes it to have the highest electron affinity of all of the elements.

What is electron affinity of nitrogen?

Electron Affinity of Nitrogen is 7 kJ/mol.

Which has more electron affinity beryllium or nitrogen?

Nitrogen and beryllium have same number of shell but nitrogen has more protons in it’s nucleus which result in More nuclear force than Beryllium.So,nitogen has more affinity for oxygen than beryllium.

Why is nitrogen electron affinity positive?

Since electron affinity is associated with the “love” for acquiring another electron, and the new electron would be added in one of the singly-occupied p orbitals, we have a problem. This extra energy needed to overcome the repulsion makes the electron affinity positive.

Which of the element has highest electron affinity?

What is the electron affinity of an oxygen atom?

Electron affinity of Oxygen is 141 kJ/mol. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion .

What is the electron affinity of boron and nitrogen?

The negative ions of boron and nitrogen are found to be unstable, the electron affinity being ca – 0.14 and – 0.72 ev, respectively. The electron affinities of carbon and oxygen atoms are 1.75 and 1.13 ev, respectively.

What is the over riding factor of electron affinity?

The over-riding factor is therefore the increased distance that the incoming electron finds itself from the nucleus as you go down the group. The greater the distance, the less the attraction and so the less energy is released as electron affinity.

Which is smaller an oxygen atom or a nitrogen atom?

Here one can see that there is no real difference in the orbitals that would add more volume to the oxygen. Oxygen does however have one more proton. This will have a greater pull on the electrons, making oxygen a smaller atom. So oxygen has higher electron negativity than nitrogen.
