Fluorine has a higher charge than iodine because fluorine is more electronegative than iodine. This means that fluorine has a greater ability to attract electrons towards itself, resulting in a higher charge. Additionally, fluorine's smaller size allows it to exert a stronger pull on electrons compared to the larger iodine atom.
What else can I help you with?
Does Iodine have less electron affinity than fluorine?
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine
How is Fluorine electronegative than iodine?
Fluorine is more electronegative than iodine because it is smaller in size and has a greater nuclear charge. This results in stronger attraction for electrons in a chemical bond, making it more likely for fluorine to attract and hold onto electrons compared to iodine.
What is the Oxidation number on IF7?
The oxidation number of iodine in IF7 is +7. This is because fluorine is more electronegative than iodine, so each fluorine atom in the compound carries an oxidation number of -1. Since there are 7 fluorine atoms in IF7, the total charge from fluorine is -7, which means iodine must have an oxidation number of +7 to balance the charge.
What is the oxidation number of IF?
The oxidation number of iodine in IF is +1 because fluorine is more electronegative than iodine and will take on a charge of -1. Since the compound is neutral, the oxidation number of iodine must be +1 to balance the -1 charge of fluorine.
Why is the ionisation energy of fluorine higher than iodine?
The best modern answer would involve quantum chemistry, but an easier to understand explanation is that the outermost electrons in fluorine are much closer to the nucleus that provides the attraction to hold the electrons and nucleus together as an atom than are the outermost electrons in iodine. This is sometimes called the "screening effect" of inner shell electrons that weakens the attraction between the nucleus and the outer shell electrons in large atoms such as iodine.
Will fluorine replace iodine in a reaction?
Fluorine is more reactive than iodine, so fluorine can displace iodine in a chemical reaction to form a compound. This displacement reaction occurs because fluorine has a higher electronegativity and stronger oxidizing ability than iodine.
Does Iodine have less electron affinity than fluorine?
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine

Is iodine a positive or negative charge?
No, nitrogen is more electronegative than iodine. Electronegativity of nitrogen= 3.04 Electronegativity of Iodine = 2.66
Why boiling point of fluorine is less than iodine?
The boiling point of fluorine is lower than that of iodine primarily due to the differences in molecular size and intermolecular forces. Fluorine, being a smaller molecule with weaker London dispersion forces, requires less energy to transition from liquid to gas compared to iodine, which is larger and has stronger dispersion forces due to its greater number of electrons. Consequently, iodine's higher molecular weight and stronger intermolecular interactions result in a higher boiling point.
Why is the ionisation energy of fluorine higher than iodine?

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.
Does fluorine have weaker or stronger intermolecular forces than iodine?
It depends. If Fluorine is bonded to Hydrogen then it would be greater, having present Hydrogen Bonding-the strongest Intermolecular Force. Iodine,I2, has many more electrons than fluorine, F2,so London dispersion forces are much stronger explaining why fluorine is a gas and iodine is a solid under standard conditions.
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.
Why are bromine and iodine denser than fluorine and chlorine?
Bromine and iodine are denser than fluorine and chlorine due to their larger atomic sizes and greater atomic masses. The increase in size and mass of bromine and iodine atoms results in stronger van der Waals forces between the molecules, which leads to higher density.
