∙ 14y agoMost metals have high boiling points. The elements with the highest boiling points are rhenium and tungsten, which have boiling points of over 5000oC. The non-metal element with the highest boiling point would be the carbon, in its diamond structure.

Why methane and silicon dioxide have different boiling points?
They're very different compounds in nearly every way; it would be considerably more surprising if they had similarboiling points.
Which type of compound would have the lowest melting point?
Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.
How can iodine have a melting point?
All substances have melting points and boiling points. A melting point is merely the temperarture at which it changes from a solid to liquid and vice versa. The boiling point of a substance would be the temperature at which it changes from liquid to gas and vice versa.
What are the typical properties of ionic compound?
low melting point. ionic compounds have high melting and boiling points. They conduct electricty in solution or in molten state unlike covalent compounds and carbon compounds which are poor conductors of electricity .
What is the boiling point of H2O?
100 degrees C or 212 F is the boiling point of pure water. However, due to impurities such as sodium and calcium compounds being present in most water, the boiling point is likely to be slightly higher.
Do organic compounds have a higher boiling point?
Higher than what? Some organic compounds (e.g. propane, butane) have very very low boiling points making them gases at room temperature. Certain inorganic compounds (e.g. tungsten carbide) have boiling points so high that before those compounds boiled all organic compounds would not only have boiled but would have decomposed into their elements or very simple inorganic carbon compounds (e.g. carbon monoxide, carbon dioxide).
How would you use the boiling point of a substance to identify a specific substances?
Because each compound has a specific boiling point (with some exceptions) comparing exactly determined boiling points we can identify compounds.

Organic compounds are also covalent compounds what properties would you expect organic compounds to have as a result?
They have a higher boiling point and lower melting point and is flamable.
What forces would cause the highest boiling point?
These are ionic bonds.
What attractive force would cause the highest boiling point?
These are ionic bonds.
In what situation would you use fractional distillation over simple distillation?
You would use simple distillation when the two products you are trying to separate have large difference in boiling points. Fractional distillation is needed when the two products have very close boiling points (like Hexane and toluene). In petroleum refining, the word "fractionation", not "fractional distillation" is used, often interchangeably with "distillation". When we have a crude mixture of different compounds which have very minor difference in their boiling points and cannot be separated simple distillation, then fractional distillation is used. Differenciation of components of petroleum is done by this process
What types of mixture do fractional distillation separate?
for mixtures that are miscible but have different boiling points
Do metals melt easily?
If easily means at low temperatures then no, ionic compounds generally have a higher melting point than most compounds except for those with hydrogen bonding and network covalent bonding which have higher melting points generally.
You are given the melting points of three unknown substances and are asked to predict which one is an ionic compound You would select the compound with the?
Highest melting point. (Note that this does not assure that the remaining compounds are not also ionic.)
How would you describe the boiling points of water?
That is when the particles in H20 are at its maximum kinetic energy.
