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.
SiH4. since it's mass is larger then CH4, London constraints are stronger.
This element is chloroine: -34,04 oC.
Cl2 has the lowest boiling point of these four substances.
Boiling point is -34,04 oC.Melting point is - 101,5 oC.
NaCl has ther highest melting point, as it is a solid at room temeprature. The other are gases and there fore have much lower boiling points and lower again for melting points.
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

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.
(It has a melting point of-150.7 degrees Fahrenheit and a boiling of -29.27 degrees Fahrenheit.) Chlorine Melting point is 172 Kelvin (which is also its freezing point) Chlorine's boiling point is 239 Kelvin (which is also its condensing point) For reference, water freezes at 273 Kelvin and boils at 373 Kelvin. This means that chlorine will remain a gas until quite cold temperature of about negative 34 degrees centigrade. Those numbers above are valid under atmosphere pressure 14.7 PSI As soon as pressure changes, especially when Cl2 is being transferred through piping, boiling point ( condensing point) will also go higher. For example; Cl2 is in gas form at 25 PSI if temperature is 24F (-4C , or 268K ) If you increase the pressure in your pipe up to 65 PSI for transferring to further points then CL2 gas condenses (liquiifies) in the pipe. Reason is condensing temperature at 65 PSI is 54F (12C , or 285K)
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

Molecules of a halogen e.g. Cl2 are attracted together the weak Van Der Waals forces. these forces can be easily broken with a very small amount of heat, meaning that these halogens have very low boiling points, this allows the halogen to exist as a gas naturally due to its low boiling point.
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.
