In the Periodic Table of elements, fluorine and iodine are in the same column, but fluorine is in the second, iodine in the fifth row.
That means fluorine has only nine electrons flying around in orbitals while iodine has 53 of them.
Ionization is the called a process during which a single electron is abstracted - we're now talking about the 1st ionization energy, which is much higher for fluorine. Well, as it only has nine electrons scattered in the orbitals (but according laws, of course), they do not really influence the repelling - attracting actions between the positive center and the other electrons beside them.
For iodine with 53 electrons, they really do interfere with the attraction of other electrons AND as the outmost electrons (which are the ones taken away by ionization) are in those orbitals which are at the biggest distance to the center - for 53 electrons the outmost orbitals is at a much bigger distance... both results in a smaller attraction of the electrions at max distance from the center... so for iodine you need less energy to perform ionization.
What else can I help you with?
Which element has a higher first ionization energy than chlorine Cl?
The element with a higher first ionization energy than chlorine Cl is fluorine F. Fluorine is located to the left of chlorine in the periodic table, which means it has a smaller atomic radius and stronger nuclear attraction, requiring more energy to remove an electron.
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.
Does argon or chlorine have a higher ionization energy?
Argon has a higher ionization energy than chlorine. This is because argon is a noble gas with a full valence shell, making it more stable and harder to remove an electron from compared to chlorine which is a halogen with one electron missing from a full octet.
Does sodium or chlorine have a higher ionization energy?
The second ionization energy of sodium is so much greater than the first because the first electron is removed from the valence shell, while the second electron is removed from the core orbitals. Additionally, the sodium atom has a positive charge after the first ionization, which thus attracts the remaining electrons more strongly. Both of these factors lead to a much higher second ionization energy compared to the first.
Does potassium or bromine have a higher ionization energy?
Bromine has because the ionization energy increases as you move across and decreases as you move down.
Does Chlorine has a higher ionization energy than fluorine?
No, fluorine has a higher ionization energy than chlorine. Fluorine is the most electronegative element in the periodic table, meaning it has a strong attraction for electrons and therefore requires more energy to remove an electron compared to chlorine.
Which element has a higher first ionization energy than chlorine Cl?
The element with a higher first ionization energy than chlorine Cl is fluorine F. Fluorine is located to the left of chlorine in the periodic table, which means it has a smaller atomic radius and stronger nuclear attraction, requiring more energy to remove an electron.
Does fluorine have a higher ionization energy than bromine?
yes because ionization energy increases up and to the left on the periodic table. and fluorine has the highest ionization energy because it is so close to becoming a noble gas it tears off electrons from everything to complete the octete
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.
Is chlorine higher in ionization energy than aluminum?
Yes, chlorine has a higher ionization energy than aluminum. Ionization energy generally increases across a period in the periodic table due to increasing nuclear charge and decreasing atomic radius. Chlorine is located to the right of aluminum in the periodic table, making its ionization energy higher. Specifically, chlorine's ionization energy is about 1251 kJ/mol, while aluminum's is around 577 kJ/mol.
Which element in each pair has the greatest ionization energy fluorine or iodine?
The ionization energy of fluorine is 1681 kJ/mol (the first) and the ionization energy of iodine is 1008,4 kJ/mol.
Why does boron have a higher ionization energy than fluorine?
Because fluorine's size is lower than that of iodine, it has a greater ionization energy than iodine. Fluorine, on the other hand, appears to have a smaller shielding effect. As a result, fluorine's nucleus attracts more valence electrons than iodine's.
What element has a higher first ionization energy then carbon?
Halogens, specially fluorine
What has a higher ionization energy between sodium and chlorine?
Chlorine has a higher ionization energy than sodium. This is because chlorine has a smaller atomic size and higher effective nuclear charge, making it more difficult to remove an electron compared to sodium.
Sodium an alkali metal and chlorine a halogen are both in Period 3 of the periodic table Which element has a higher ionization energy?
Chlorine has a higher ionization energy than sodium. This is because chlorine, being a halogen, has a stronger electron affinity and is closer to achieving a stable electron configuration by gaining an electron, leading to a higher energy needed to remove an electron from its outer shell.
Does fluorine have a higher ionization than xenon?
Yes, fluorine has a higher ionization energy than xenon. Fluorine is a smaller atom with a stronger nuclear charge, making it harder to remove an electron compared to xenon, which is a larger atom with more electron shielding.
Is magnesium's ionization energy higher or lower than chlorine?
ionization energies of mg is less than chlorine because chlorine requires only one electron to complete its octet so it will not prefer to loose its electron morover its electronegativity is also higher and it is of smaller size than mg so electtron removal is difficult
