Why chlorine is gas but iodine is solid?

Explanation: Iodine is present in solid form at room temperature while chlorine is a gas at room temperature because of the difference in intermolecular forces that act on between individual molecules. Iodine has atomic number 53 while chlorine has 17, so iodine has more electrons in its electron shells.

Why chlorine is a gas bromine is a liquid and iodine is a solid at room temperature?

Whether a substance is a solid, liquid, or gas depends on the balance between the kinetic energies of the molecules and their intermolecular attractions. 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 fluorine is gas while iodine is solid?

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.

Is iodine 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 chlorine gas and bromine 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 chlorine a solid liquid or gas at room temperature?

Chlorine is a greenish yellow gas at room temperature and atmospheric pressure. It is two and a half times heavier than air. It becomes a liquid at −34 °C (−29 °F).

Is chlorine a solid liquid or gas?

Why is chlorine a gas and bromine a liquid?

Is chlorine a gas solid or liquid?

Why is chlorine a gas?

In Cl2 there are covalent bonds between the atoms forming simple molecules. There are weak attractions between molecules of Cl2 meaning little energy is needed to break these forces of attraction and therefore Cl2 has a low boiling point.

Why is iodine a solid at room temperature and chlorine gas?

Why is iodine a solid at room temperature and chlorine a gas, despite being in the same group? Even though they are divalent molecules, iodine has more electrons per molecule than chlorine which means that iodine has more contact surfaces for intermolecular forces to act on between individual molecules.

Why is iodine a solid and bromine a liquid?

In the periodic table the vander waal ‘force increase down the group. Cl has weak fotce of attraction,it is gas. While bromine has strong force of attraction then Cl so it is liquid. And Iodine has last member of halogens in the group it has the strongest vander waal force among halgens so it is solid

Why is chlorine Cl2 a gas at room temperature?

Why is chlorine Cl2 a gas at room temperature bromine Br2 a liquid and iodine I2 a solid? At 25oC, chlorine (Cl2) is a gas whereas bromine (Br2) is a liquid. As the elements are cooled, the kinetic energy of the Cl2 and Br2 molecules decreases and the London forces are strong enough to overcome the kinetic energy and hold the molecules in a solid.

What is the difference between iodine and fluorine?

Iodine is a solid while fluorine is a gas although both are halogens because the metal (reducer) character of elements increases when you going down the groups of the Periodic table. Iodine has even brilliance, similarly as metal.
