Best Answer

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 :)

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.
