Why does silicon have a high melting point while argon has a low melting point?
Kooikeria
Silicon is a covalent macromolecule. Argon, on the other hand, only has weak Van der Waal's force.

What is the boiling point of silicon carbide?
Sulfur dioxide has a boiling point of −10°C (14°F) while silicon dioxide has a boiling point of 2230°C (4046°F). With these numbers in mind the difference would be 2240 °C (4064°F).
Explain why silicon's atom is larger than argon's atom?
Silicon is larger than Argon for several reasons: If the electron configuration is examined, it becomes clear. Si has the configuration [Ne]3s23p2 while Argon's is [Ne] 3s23p6 As you can see, both elements have valence electrons in the same energy level, the p orbital, but Argot has more protons in its nucleus, so therefore, it's pull of the electrons to it's core is higher than that of Silicon. So, Argon is SMALLER than Silicon. Hope this helped.
Why is the boiling point lower than melting point?
It is the opposite. The boiling point is greater than the melting point. for example for fresh water, the boiling point is 100 centigrade while the melting point (for ice) is zero.
When are oil baths and water baths used respectively for melting point determination?
oil is used when we are determining the melting point of compound higher than 100 while for those compound which have melting point less then 100 we use water bath
Is the melting point of BaCl2 higher than the melting point of CaCl2?
Yes; the M.P of BaCl2 is about 963 Celsius while that of CaCl2 is about 782Celsius.

How are boiling point and melting point different?
Boiling point is the temperature point at which a liquid becomes a gas while melting point is the point at which a solid becomes a liquid.
Why is the boiling point lower than melting point?
It is the opposite. The boiling point is greater than the melting point. for example for fresh water, the boiling point is 100 centigrade while the melting point (for ice) is zero.
What is purity criteria?
The criteria of purity of a compund isÊdetermined at it melting point.ÊA pure compound a definate melting point. While an impure substance has an indefinate melting point.
What happens to neon during melting point?
There are a number of things that could happen to neon while it is at its melting point. It could melt.
How does salt raises the melting point of water?
It doesn't increase the melting point of ice, instead, it lowers it. When a solute (which is the salt) is added to a solvent (which is what dissolves it), the boiling point is increased while both the freezing and melting points are decreased. This is evident in the boiling point elevation and the freezing/melting point depression system.
Why urea has sharp melting point but glass does not?
Urea is a pure crystalline compound so has a sharp melting point while glass is an amorphous mixture.
What compound has the higher melting temperature Strontium Sulfate or Magnesium Oxide?
Magnesium Oxide Strontium Sulphate has a melting point of 1606°C while Magnesium Oxide has a melting point of 2852°C
When are oil baths and water baths used respectively for melting point determination?
oil is used when we are determining the melting point of compound higher than 100 while for those compound which have melting point less then 100 we use water bath
Do solids have a low melting point?
Some do while others do not. To be solid a substance must merely have a melting point that is above room temperature. Gallium has a melting point just above room temperature, so it is normally solid but it will melt in the palm of your hand. By contrast Tungsten has such a high melting point that not even the hottest lava from Earth's volcanoes can come close to melting it.
How do you determine the type of compound ionic or molecular from the melting point such as 1240 degrees C?
If the melting point is at 1240 degrees C then it is most likely an ionic compound, because ionic compounds have their melting points above 800 degrees C while the molecular compounds have their melting point at or below room temperature.
