Why silicon has the highest melting point and argon has the lowest?

Silicon has the great molecular form which makes it very strong and requires a lot of energy to break this bonds. However, Argon has the lowest melting point because it has weak Van Der Waals forces which barely keeps this atoms together, so it does not require a lot of energy.

What temperature does argon become a gas?
the freezing temperature of Argon is-189 celsius.(melting)
What has a melting point of -183?
There is no element with a melting point of -183 deg C. The nearest element is Argon, with a melting point of -189 deg C.
What is lowest second ionization energy on argon calcium or potassium?
calcium
Which two elements from boron carbon nitrogen oxygen fluorine neon aluminum silicon phosphorus sulfur chlorine and argon are the most stable?
Among these, neon and argon are most stable, as they are noble gases and have completely filled orbitals.
Describe General trend in physical appearance of the elements in period 3?
Sodium, magnesium and aluminum are all good conductors of electricity. Silicon is a semiconductor.Sodium, magnesium and aluminum all have metallic structures, which accounts for their electrical conductivity and relatively high melting and boiling points.The nuclei of the atoms gets more positively charged.Melting and boiling points rise across the three metalsSilicon has the highest melting point.Phosphorus, sulphur, chlorine and argon are simple molecular substances with only van der Waals attractions between the molecules. Their melting or boiling points will be lower than those of the first four members of the period which have giant structures.These four substance with simple molecular structures also do not conduct electricity.
Why does silicon have a high melting point while argon has a low melting point?
Silicon is a covalent macromolecule. Argon, on the other hand, only has weak Van der Waal's force.

Which element is most similar to oxygen bromine argon or silicon?
silicon
Why is the melting point of silicon much higher than that of argon even though argon has a greater molar mass?
Because Argon exists as diatomic Ag2 molecules, with relatively weak inter-mocular forces (Van-der-Waals forces) between the molecules. Melting Argon only requires that these inter-olecular forces are overcome, which does not requires much energy as the molecules are small - so Argon melts at -189 degrees celcius - so is a gas at R.T.P Silicon on the other hand exists in a macro-molecular form, and all the atoms are covalently bonded to each other in a giant molecular lattice. To melt silicon, covalent bonds must be broken, which requires a great deal of energy, and hence silicon only melts at 1414 degrees celcius
Why does argon have a low melting point?
Argon is a monoatomic element.
