Which has more electron affinity phosphorus or sulfur?
Since the 3p electrons in sulfur (that sulfur would lose) are paired, sulfur has more electron repulsion in those orbitals than phosphorus does, so it takes less energy input to remove an electron from sulfur.
What is the electron affinity of phosphorus?
Electron Affinity of Phosphorus is 72 kJ/mol.
Why is the electron affinity of/p less than S?
However, in order to form P-, the extra electron must pair up with an existing electron in one of the p-orbitals. The extra repulsion involved leads to the electron affinity being lower for P than for Si despite the higher nuclear charge.
Does sulfur have electron affinity?
The electron affinity of sulphur is – 200 kJ/mol.
Which has higher ionization energy p or S?
(4) In this situation, the effect of an increase in nuclear charge in phosphorus is greater than the repulsion between its 3p electrons. A. The first ionisation energy of phosphorus is greater than that of sulfur.
Why phosphorus has higher ionization energy than sulphur?
Because Phosphorus has outermost electronic configuration P3 and Sulfur P2, P3 is half filled orbital, so more energy is required to remove outermost electron than P2. That’s why phosphorus has more ionization energy than sulfur.
Which has more electron affinity?
Halogens has higher electron affinity and it is supposed to be for fluorine, but chlorine has higher electron affinity than fluorine due to fluorine’s smaller size. Hence, among given options chlorine has highest electron affinity.
Is electron affinity of phosphorus is less than nitrogen?
Nitrogen has a lower electron affinity than phosphorous.
Why is electron affinity of phosphorus greater than nitrogen?
Solution : Electron affinity, in general decreases down a group. However, electron affinity of P(70) is more than N(0). It is due to the releatively compact 2p-subshell. Thus, electron affinity of P is more than N and As.
Who has more electron affinity O or S?
Solution : `S` has high electron affinity because in oxygen there is ‘more interelectronic repulsion than sulphur, therefore, more energy is released in case of sulphur on gaining electrons . ‘
Why the ionization energy of phosphorus is more than sulphur?
Solution : Phosphorus contains half-filled 3p orbitals, have extra stability. So, the removal of an electron from phosphorus atom requires more energy than sulphur.
Why do phosphorus and sulfur have almost the same ionization energy?
While in phosphorus there are 2 paired electrons and 1 lone electron in the 3p level. Due to the electron repulsion of the paired electrons in sulfur, less energy is required to remove 1 mole of electrons from its sub-level, as there is less of an attraction of these electrons towards its nucleus.
Which is more stable phosphorus or sulphur?
Why does first ionisation energy decrease from p to S?
Slight decrease in IE from P to S For sulfur, electron is removed from a fully filled 3p orbital hence it experiences interelectronic repulsion between the electron pair in the same 3p orbital. This makes it easier to remove that electron, therefore S has a lower first IE.
Why sulphur has higher electron affinity than oxygen?
The electron affinity of sulfur is greater than oxygen. Why? Solution : This is because of smaller size of oxygen due to which it has got higher change density and thus electronic repulsion increases as it takes electron. So its E.A. is less than sulphur.
Which has higher electron affinity nitrogen or phosphorus?
Which has more electron affinity oxygen or sulphur?
This repulsion is higher for oxygen due to its small size and higher electron repulsion. So electron affinity is more in sulphur than oxygen.
How do you find electron affinity?
The amount of energy released when a neutral atom in its gaseous state accepts an electron and gets converted into a negatively charged ion is known as electron affinity. X ( g ) + e − → X − ( g ) + E . A . Therefore, the electron affinity of chlorine is – 349 KJ/mol.
