Why cl2 is gass and br2 liquid and I2 solid?

Answer 1

NaCl is ionically bonded with stong electrostatic attractions whereas Cl2 only has weak Van Der Waals' forces acting between the molecules More strength is needed to break NaCl's bonds than CL2's bonds. Therefore, NaCl is solid and Cl2 is a gas Hope this helps :)

Answer 2

This question is asking about the intermolecular forces between the molecules of Cl2 ect...

The force that exists between these molecules is London Dispersion forces which refer the random arrangement of electrons at any given time in in the molecule, this leads to instantaneous dipoles and givens the molecule an interatomic

attraction to a neighboring molecule. Cl2 is a gas because it has the least electrons and protons, and the strength of it's pull at any given time will be less than Br2 and I2 successively, whom both have a larger number of protons and electrons and their spontaneous strength of pull is larger, giving overall stronger intermolecular forces. Br2 being less than I2.

Answer 3

The physical state of an element at room temperature depends on its intermolecular forces. Cl2 is a gas because the chlorine atoms are held together by weak London dispersion forces. Br2 is a liquid due to stronger London dispersion forces, while I2 is a solid because it forms even stronger van der Waals forces.

Answer 4

Molecules of I2 have stronger intermolecular forces than molecules of Br2

Answer 5

Molecules of I2 have stronger intermolecular forces than molecules of Br2.

Answer 6

Yes, it is correct.
