Reason for why gaseous Bromine is reddish brown and transparent whereas liquid Bromine is dark brown and passing of light is little has to be explained using postulates of Kinetic-molecular theory.

Question

Examining the crystal structure of CsCl (Caesium Chloride), the Cs+ions form the 8 corners of a cube and the Cl−ion is a the center of the cube. From first-principles calculation, it was determined that the lattice constant of CsCl is 4.209 ̊A. (a) Calculate in detail the electrostatic force exerted by all the Cs+ atoms to the Cl−atom; (b) Assuming that 1 Cs+atom is missing in crystal structure (crystal is said to have a defect), calculate in detail what will be the net electrostatic force on the Cl−ion due to the remaining Cs+ions.

Neon and HF have approximately the same molecular mass. (a) Explain why the boiling point of Neon and HF differ. (b) Compare the change in the boiling points of Ne, Ar, Kr, and Xe with the change of the boiling points of HF, HCl, HBr, and HI, and explain the difference between the changes with increasing atomic or molecular mass.

Coulombs Law describes the interaction between two charges and varies by the magnitude of these charges and inversely with the distance between them. For atoms, we'll label the charges as the nuclear charge and electron charge. 9192 9nuclelec As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge on the nucleus increase, so that in general. qnuc = Z ·(+1) However if we think only of the electrons in the outermost shells (valence electrons), they do not see the full strength of the nuclear charge because it is partially shielded (or canceled out if you prefer) by the core electrons. So we define something called effective charge. Shielding Experiences net charge of about 1+ Nucleus Effective Charge = # of protons Zeff = Z – core # of core electrons In general, Zeff increases as you go across in the periodic table. 1. Fill out the following table to verify that effective charge increases as you go across a row. Element Na Mg Al Si P S CI Ar…
