Yes non metals do have high melting and boiling points. This is because they have strong intemolecular forces that are hard to overcome.
A2. Their melting points vary. Obviously gases such as nitrogen and oxygen have low melting points, but Silicon (1414oC) and Diamond ( around 1700oC) are rather high. Phosphorous and Sulfur on the other hand are rather low.
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
The melting points for non-metals range from the lowest for all elements to the highest. The melting point for Helium is effectively 0 K (-273.15 deg C) whereas that for Carbon is 3823 K (3550 deg C).
Name your glue - there are thousands of types with many different melting points .!
There are hundreds of different glues, with different melting points, setting times and means of adhesion.
- many nonmetals are gaseous or liquids- densities are not high- hardness of solid elements is not high- nonmetals form frequently anions- nonmetals form frequently compounds with covalent bonds
No, the trends for melting points and boiling points in nonmetals are generally different from those in metals. Nonmetals typically have lower melting and boiling points compared to metals, which tend to have high melting and boiling points due to strong metallic bonds. In nonmetals, the melting and boiling points can vary significantly based on molecular structure and intermolecular forces, with noble gases having very low points and some covalent network solids like diamond having high points. Therefore, while both groups exhibit trends, the underlying reasons and values differ significantly.
Nonmetals typically have lower melting points and boiling points compared to metals. This is due to nonmetals having weaker intermolecular forces, such as van der Waals forces, compared to the strong metallic bonds found in metals.
Metals are malleable (can be shaped and formed), conductable (electricity), and have high melting points. Nonmetals are brittle, cannot conduct electricity, and have very low melting points.
positive ions have high melting points
They are poor conductors
Metalloids have melting points that are generally lower than those of metals but higher than those of nonmetals. Their melting points can vary depending on the specific element and its atomic structure.
Nonmetals generally have low melting and boiling points. This is because the forces of attraction between nonmetal atoms (van der Waals forces) are weaker compared to metallic or ionic bonds, resulting in easier breakage of these bonds at lower temperatures.
metal- shiny non-metal- dull
These are transition metals (Ti, Zr, Hf, Rf), with high melting points, resistant to corrosion, reacting with nonmetals, being tetravalent.
They have low melting points and high reactivity.
It varies. Boron and thallium both have relatively high melting points while gallium and indium have very low melting points.
In general, ionic compounds have high melting points due to the strong electrostatic forces holding the ions together in a lattice structure. This results in a significant amount of energy required to break these bonds, leading to high melting points.
