it has a boiling point of about 3700 degree Celsius
Diamond is an allotrope of carbon where all the carbon atoms are tetrahedrally bonded with each other forming a three dimensional covalent network. Since the bonds are strong (covalent, network), diamond has a very high melting point and boiling point. Iodine does not have three dimensional network and hence has very low melting/ boiling point. It fact, it will sublime at room temperature.
Diamond does not have a boiling point because it sublimes directly from solid to gas at extremely high temperatures. Graphite also does not have a boiling point, as it too sublimes at high temperatures.
Diamond is pure carbon with a specific crystalline structure.
One example of a solid that has a high boiling point and is not malleable is diamond. Diamond is a form of carbon with strong covalent bonds arranged in a crystal lattice structure, which makes it extremely hard and with a high boiling point. Despite its hardness, diamond is not malleable because its crystal structure does not allow for easy deformation.
The boiling point of fluorine (F) is -188.12 degrees Celsius (-306.62 F). The boiling point of carbon (C) in the form of a diamond is about 4027 degrees Celsius (7281 F). This value will vary depending on how the carbon is formed.
i think it is 2400c but I'm not sure if that is just for carbon
Boiling is the phase where the boiling occurs. The point at which the boiling occurs is the boiling point.
Diamond is a unique nonmetal because its structure consists of a three-dimensional network of carbon atoms covalently bonded, making it extremely hard and having a high melting point. Additionally, diamond has a high refractive index and exceptional thermal conductivity, distinguishing it from other nonmetals.
Methane consists of separate CH4 molecules that can move freely and are only weakly attracted to one another. Diamond consists of a covalent network in which each carbon atom is strongly bonded to its neighbors.
there is no boiling point
Tungsten has the highest boiling point of the elements. See link below. (Note that Wikipedia has a different value than you give in the question, 5828K or 5555°C.) I checked some standout minerals, and they all boil at lower temperatures CaF2, even carbon (diamond, graphite). Note that "boiling point" can be adjusted by changing the pressure, as with anything.
Whether or not the boiling point of neon is negative depends on the temperature scale used to describe the boiling point. If the boiling point is given in Celsius or Fahrenheit, the boiling point is negative. However, in Kelvin, which cannot be negative, the boiling point is positive.
