The boiling point in degree Celsius are given below:
Na: 883
K: 774
Si: 2355
Ne: -246
Silicon has the highest boiling point among the elements given.
Boiling point is -34,04 oC.Melting point is - 101,5 oC.
NaCl has the highest melting point among the compounds listed at 801°C, followed by Cl2 at -101°C, then HCl at -114°C, and finally HF at -83°C.
The lowest boiling point among CuCl2, HF, and MgCl2 is HF. This is because HF is a molecular compound with weaker intermolecular forces compared to the other two, which are ionic compounds with stronger electrostatic interactions between ions.
Boiling point of SiCl4 is lower than expected. Its chlorine atoms have higher negative charge due to lower electro negativity of silicon. Therefore the molecules repel each other. this results in lower b.p of SiCl4
HCL has a higher boiling point compared to HBr This is due to difference in electronegativity. H - 2.1 Cl - 3.0 Br - 2.8 The difference for HCl is 0.9, the difference for HBr is 0.7. The larger the difference in electronegavity means the stronger the bond. Large difference means greater attraction hence more energy is needed to overcome this bond.

NaCl is an ionic solid with a high boiling point. Cl2 is held together by weak dispersion forces and is a gas at room temperature. That means Cl2 has already boiled and formed a gas at a temperature lower than room temperature.

This is AsCl3 (I don't understand Ver).
Chlorine is an element, and by itself forms Cl2, which is normally a gas. From Wikipedia: Boiling point: 239.11 K (-34.4 °C, -29.27 °F). I suspect, however, that this is not what you actually wanted to know; but without knowing more about exactly what you are trying to do, I can't come up with a better answer.
Well, darling, Chlorine's boiling point is -34.04°C and its melting point is -101.5°C. So, if you're looking to boil or freeze some Chlorine, now you know the temperatures to work with. Just don't go inhaling the stuff, unless you're into that whole suffocating and burning sensation.
The element described is chlorine (Cl). It has a low melting point (-101.5°C) and boiling point (-34.04°C), exists as a diatomic molecule (Cl2) in the gas phase, has seven valence electrons, and readily reacts with metals to produce salts.
HCL has a higher boiling point compared to HBr This is due to difference in electronegativity. H - 2.1 Cl - 3.0 Br - 2.8 The difference for HCl is 0.9, the difference for HBr is 0.7. The larger the difference in electronegavity means the stronger the bond. Large difference means greater attraction hence more energy is needed to overcome this bond.
The two factor Van de Waals gave as correction for real molecules instead of the ideal gas, are the size of the molecule, and the amount of attraction between the molecules. The larger the size of the molecule for the greater the deviation from an ideal gas, clearly bromine wins here since it has the biggest size of its atom. The amount of attraction between molecules is directly proportional to the boiling point of the liquid made from those molecules, and again bromine wins here since its has the highest boiling point. So bromine has the greatest deviation from ideal gas behaviour.
