Top best answers to the question «Noble gas have zero electron affinity why»

Electron affinity of noble gas is near zero. Noble gas has completely filled valence shells and stable octets. It does not accept electrons easily as they have no deficiency, also adding electrons produces repulsion between the electrons.

Electron affinity of noble gases is practically zero. They have no affinity for additional electrons because they already have achieved a stable, inert-gas electronic configuration (all orbitals filled and spin-paired up). The heavier noble gases (Xn, Kr) can engage in compound formation with highly electronegative elements (e.g. fluorine).

Electron affinity of an element is the energy released when an element in the gas phase gains an extra electron to form an anion. Noble gases have a completely filled valence shell and does not require any extra electron to become stable and so has a zero electron affinity.

Since the Noble Gases already have that 'perfect status' then they have an affinity of 0. Affinity is the change in energy of the atom when an electron is added. Noble Gases are at the perfect number of 8 electrons. They don't 'want' anymore electrons, so there's zero change in the energy of the atom. p.s. This is also why they are the least reactive elements on the table.

Because it is stable and completely full filled electrons so it don't want any electron. As Noble gases have complete electronic configuration so the tendency of the noble gases to gain or loss an electron is negligible.... Therefore, the electron affinity of noble gas is zero.

Electron affinity of noble gas elements is zero. Reason. Electron affinity reflects the ability of an atom to accept an electron. It is the energy change that occurs when an electron is added to a gaseous atom. Atoms with stronger effective nuclear charge have greater electron affinity. A.

0. This is because all of the Noble Gases have complete valence electron shells. Most elements 'want' to have a complete electron shell with 8 electrons. Since the Noble Gases already have that 'perfect status' then they have an affinity of 0. Affinity is the change in energy of the atom when an electron is added. Comment.

Most elements want to have a complete electron shell with 8 electrons in the outtermost shel except 1st period. Since the Noble gases already have that perfect configuration so they have 0 affinity to electron. Answer verified by Toppr 179 Views

This causes the noble gases to have essentially zero electron affinity. Why do noble gasses have high electron affinity? This is because all of the Noble Gases have complete valence electron shells. Since the Noble Gases already have that ‘perfect status’ then they have an affinity of 0. Affinity is the change in energy of the atom when an electron is added. Noble Gases are at the perfect number of 8 electrons.

This causes the noble gases to have essentially zero electron affinity. Why is the electron affinity so positive for the noble gas elements? Explanation: This is because all of the Noble Gases have complete valence electron shells. Since the Noble Gases already have that ‘perfect status’ then they have an affinity of 0.
