Does phosphorus have a higher electron affinity than 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. Hence, since the ionization occurs more easily, the ionization energy is smaller.
Why is the ionization energy of phosphorus higher than that of sulfur?
As we know that half filled and full filled orbitals has higher stability as compared to partially filled orbitals. Hence Phosphorus is more stable than Sulphur, which makes it harder to extract an electron from Phosphorus and hence first ionization enthalpy of Phosphorus is higher than that of the Sulphur.
Does phosphorus have a high electron affinity?
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.

| Electron affinity (kJ/mol) | 72.037(1) |
What causes higher electron affinity?
Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons.
Why phosphorus has lower electron affinity than silicon?
Re: Electron Affinity Relationship of C and N. This is because of the p orbitals of these elements. For example, phosphorous has its 3P orbital half-filled which is fairly stable so when one more electron is accepted the stability is disturbed. This is why the electron affinity of phosphorous is less than silicon.
Does phosphorus have a higher or lower first ionization energy than sulfur?
B. The first ionisation energy of phosphorus is less than that of sulfur. (1) More energy is required to overcome the attraction between the paired 3p electrons in sulfur. (2) 3p electrons of sulfur are further away from the nucleus compared to that of phosphorus.
Why is electron affinity of phosphorus greater than nitrogen?
This means phosphorus has more occupied electron shells than nitrogen. So nitrogen will have a smaller atomic radius. This means the electrons are closer together. So, the reason that the change in energy for both electron affinities is lower for atoms of phosphorus than for atoms of nitrogen is answer choice (B).
Why does phosphorus have a different electron affinity?
Why is the change in energy for both electron affinities lower for atoms of phosphorus than for atoms of nitrogen? [A] An atom of phosphorus has fewer electrons in its outer valence shell than an atom of nitrogen, and so there is less repulsion from the addition of electrons.
What are the factors affecting electron affinity?
Various factors that affect electron affinity are atomic size, nuclear charge and the symmetry of the electronic configuration. Atomic size: With increase in the atomic size, the distance between the nucleus and the incoming electron also increases.
