Why is I2 a solid while F2 is a gas?

In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. It is only at temperatures between -7 °C and 59 °C that fluorine and chlorine are gases, bromine is a solid, and iodine is a solid.

Why do you suppose Cl2 is a gas Br2 is a liquid and I2 is a solid?

Halogens exist as diatomic molecules at room temperature and atmospheric conditions. F2 and Cl2 are gases, Br2 is a liquid and I2 is a solid. Why? All of these molecules are completely nonpolar and according to theory, not attracted to each other, so one might predict they would all be gases at room temperature.

Why iodine exist in solid state but fluorine is gas although both are in same group?

Due to increased strength of Van der Waals forces down the group, the boiling points of halogens increase. Therefore, the physical state of the elements down the group changes from gaseous fluorine to solid iodine. Due to their high effective nuclear charge, halogens are highly electronegative.

Why is I2 a solid at room temperature while Br2 is a liquid?

The reason iodine, I2 , exists as a solid at room temperature, while bromine, Br2 B r 2 , exists as a liquid at the same temperature, is because: Iodine molecules create stronger London dispersion forces than do bromine molecules. c. Bromine exists only as a gas at all temperatures.

Is Cl2 a gas?

Chlorine is a solid, liquid or gas. The gas is 100\% elemental chlorine (Cl2), and is supplied in 150 lb cylinders (10-in. in diameter and about 55-in.

Why is Cl2 a gas and br2 a liquid?

Why? b. At 25oC, chlorine (Cl2) is a gas whereas bromine (Br2) is a liquid. London dispersion forces between the larger Br2 molecules are sufficient to cause them to form a liquid at 25oC, whereas London dispersion forces between the smaller Cl2 molecules are not.

Is F2 a solid liquid or gas at room temperature?

At room temperature, F2 and Cl2 are gases, Br2 is a liquid, and I2 is solid. The table below contains melting point data for these four substances. Use intermolecular forces of attraction to explain the trend in melting point values.

Is I2 a solid liquid or gas?

Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. The molecular lattice contains discrete diatomic molecules, which are also present in the molten and the gaseous states.

Why is fluorine more reactive compared to iodine?

Fluorine is more reactive than iodine.In the halogen group, reactivity increases from top to bottom because halogens are diatomic. Intermoleculer attraction increases from fluorine to iodine. As a result,at room temperature fluorine is gas but iodine is solid.

Why is I2 a solid?

Despite intermolecular forces being a weak individual force of attraction, collectively they are very strong and the numerous forces between iodine molecules means that more heat energy is required to break these intermolecular forces and separate the molecules therefore iodine is a solid.

What is Br2 room temperature?

Bromine
Bromine (Br, element 35), also found as a diatomic molecule (Br2), is a liquid at room temperature, solidifying at -7.2ºC.

Why is I2 a solid while Cl2 is a gas?

Problem: Why is I2 a solid while Cl2 is a gas even though they are both halogens?1. I2 is more polarizable than Cl2.2. I2 has a smaller dipole than Cl2.3. I2 is less polarizable than Cl2.4. I2 has a larger dipole than Cl2.5. I2 has H-bonding and Cl2 does not.

Why is the bond dissociation enthalpy of F2 greater than Cl2?

This is because F atom is very small and have large electron-electron repulsion among the lone pairs of electrons in F 2 molecule where they are much closer to each other than in case of Cl 2. The increasing order of bond dissociation enthalphy is I, < F 2 < Br 2 < Cl 2

How many halogens are there on the periodic table?

The Halogens. There are six elements in Group VIIA, the next-to-last column of the periodic table. As expected, these elements have certain properties in common. They all form diatomic molecules (H 2 , F 2, Cl 2, Br 2, I 2, and At 2 ), for example, and they all form negatively charged ions (H -, F -, Cl -, Br – , I -, and At – ).

Is fluorine a solid liquid or gas at low temperatures?

At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases. It is only at temperatures between -7 °C and 59 °C that fluorine and chlorine are gases, bromine is a solid, and iodine is a solid.
