Phosphorus has three unpaired electrons spread over its three 3p orbitals.
Sulphur (thank you for the old-fashioned British spelling!) has one more electron, so that one must be paired with another in the same 3p orbital. That means it will be repelled slightly, making it easier to remove.
The decrease in first ionization energy from phosphorus to sulfur occurs because sulfur has one additional electron shell compared to phosphorus. This extra electron shell results in increased shielding of the outermost electron from the nucleus' attractive force, making it easier to remove the outermost electron in sulfur compared to phosphorus.

Why does oxygen have a higher ionization energy than sulfur?
Oxygen has a higher ionization energy than sulfur due to its smaller atomic size and stronger nuclear charge. The electrons in the outer energy level are held more tightly in oxygen compared to sulfur, requiring more energy to remove an electron from an oxygen atom.
Why does phosphorus have a higher ionization energy than sulfur?
Phosphorus has a higher ionization energy than sulfur because phosphorus has a smaller atomic radius and greater nuclear charge compared to sulfur. This means that the electrons in phosphorus are held more tightly by the nucleus, requiring more energy to remove an electron. Additionally, the electron configuration of phosphorus leads to greater electron repulsion, further increasing its ionization energy.
Why does oxygen have a higher energy than sulfur?
Oxygen has a higher energy than sulfur because oxygen is more electronegative than sulfur, which means it can attract electrons more strongly. This results in oxygen forming stronger bonds with other elements, leading to higher energy content. Additionally, oxygen's smaller atomic size allows for tighter packing of its atoms in compounds, further contributing to its higher energy.
Which atom in the ground state has five electrons in its outer level and ten in its kernel?
The atom with five electrons in its outer level and ten in its kernel is a neutral sulfur atom. In its ground state, sulfur has 16 electrons distributed with 2 in the first energy level (kernel) and 2, 8, and 6 in the subsequent energy levels.
Why sulfur has a lower ionisation energy than phosphorus?
Sulfur has a lower ionization energy than phosphorus because sulfur's valence electrons are in a higher energy level, making them easier to remove. Additionally, sulfur's smaller atomic size compared to phosphorus results in stronger nuclear attraction, requiring less energy to remove an electron.
What is sulfurs ionization energy?
The ionization energy of sulfur is the energy required to remove an electron from a sulfur atom in its gaseous state. The first ionization energy of sulfur is about 10.4 electron volts (eV), while subsequent ionization energies increase as more electrons are removed.
Does Sulfur has a lower ionization energy than chlorine?
No, sulfur has a higher ionization energy than chlorine. Ionization energy is the energy required to remove an electron from an atom, and it generally increases across a period from left to right. Chlorine, being to the right of sulfur in the periodic table, has a higher ionization energy.
Why does oxygen have a higher ionization energy than sulfur?
Oxygen has a higher ionization energy than sulfur due to its smaller atomic size and stronger nuclear charge. The electrons in the outer energy level are held more tightly in oxygen compared to sulfur, requiring more energy to remove an electron from an oxygen atom.
Why does phosphorus have a higher ionization energy than sulfur?
Phosphorus has a higher ionization energy than sulfur because phosphorus has a smaller atomic radius and greater nuclear charge compared to sulfur. This means that the electrons in phosphorus are held more tightly by the nucleus, requiring more energy to remove an electron. Additionally, the electron configuration of phosphorus leads to greater electron repulsion, further increasing its ionization energy.
What is the first ionization energy of sulfur?
Firstly, you have to be familiar with the electron orbitals and how they fill. If you consider sulfur, you will notice that there are two electrons in its px orbital but only one in each of its py and pz orbitals. The two electrons in the px orbital are at different energies( one is higher than the other) and thus tend to repel each other. This repulsion causes the electrons to lose energy due to the fact that they are moving away from the nucleus and thus their attraction is lower. Therefore, the ionization energy decreases.
Which of these elements has the highest fist ionization energy sn as or s?
The element with the highest first ionization energy between Sn (tin) and S (sulfur) is sulfur (S). Sulfur has a smaller atomic radius compared to tin, making it more difficult to remove an electron from its outer shell, thus requiring more energy.
Which element has a lower first ionization energy than element S?
Element P (phosphorus) has a lower first ionization energy than element S (sulfur).
Why does oxygen have a higher energy than sulfur?
Oxygen has a higher energy than sulfur because oxygen is more electronegative than sulfur, which means it can attract electrons more strongly. This results in oxygen forming stronger bonds with other elements, leading to higher energy content.

Why sulfur has a lower ionisation energy than phosphorus?
Sulfur has a lower ionization energy than phosphorus because sulfur's valence electrons are in a higher energy level, making them easier to remove. Additionally, sulfur's smaller atomic size compared to phosphorus results in stronger nuclear attraction, requiring less energy to remove an electron.
Why does phosphorous have a higher first ionization energy than sulfur?
Phosphorus has a higher first ionization energy than sulfur due to the stronger effective nuclear charge experienced by the outermost electron in phosphorus. This is because phosphorus has one less electron shell compared to sulfur, which results in a stronger attraction between the nucleus and the outermost electron in phosphorus, making it more difficult to remove that electron.
Which atom or ion in each pair has the larger ionization energy Mg or S?
Ionization Energy is the energy required to remove an electron from an atom. In general, ionization energy increases as one approaches the upper right-hand corner of the periodic table.Sulfur is quite close to the upper right-hand corner, so it has a higher ionization energy. It is a non-metal, so it wants to accept electrons to fill its outer shell to the magic number of 8. Therefore, it is very difficult to remove one of its electrons.Magnesium, however, is a metal with two eletrons in its outer shell. Metals like to donate their electrons to reach an empty outer shell -- it doesn't even want the two electrons it has -- so it is quite easy to remove one.
