Do nonmetals have higher boiling points or lower boiling points?
Nonmetals typically have lower boiling points compared to metals because nonmetals have weaker intermolecular forces between their atoms. These weaker forces make it easier for nonmetals to break apart and transition from a solid or liquid state to a gaseous state at lower temperatures.
Do metalloids have a higher melting point then metals?
Metalloids typically have higher melting points than non-metal elements but lower melting points than most metals. This is because metalloids have properties that are intermediate between metals and non-metals, giving them melting points that fall between the two categories.
Are the trends for melting point and boiling point the same as nonmetals and explain?
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.
Why is diamond a unusual non metal?
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.
What criteria used to differnaite metals and nonmetals?
Metals are typically shiny, malleable, and good conductors of electricity, while nonmetals are usually dull, brittle, and poor conductors of electricity. Other criteria used to differentiate them include their position on the periodic table, their physical properties such as density and melting point, and their chemical reactivity.
Would metals or non metals tend to have a higher melting point?
Tungsten has the highest melting point of the elements and it is a metal.
What are three general charateristics of nonmetals?
Non metals are brittle.They are non lustrous. They have low melting point.
Do nonmetals have higher boiling points or lower boiling points?
Nonmetals typically have lower boiling points compared to metals because nonmetals have weaker intermolecular forces between their atoms. These weaker forces make it easier for nonmetals to break apart and transition from a solid or liquid state to a gaseous state at lower temperatures.
Which of these is a characteristics of nonmetals?
They are poor conductors
Why the melting point boiling point and densities of alkaline earth metals are higher than alkali earth metals?
Alkaline earth metals do not exist , only alkali earth metals
Do metalloids have a higher melting point then metals?
Metalloids typically have higher melting points than non-metal elements but lower melting points than most metals. This is because metalloids have properties that are intermediate between metals and non-metals, giving them melting points that fall between the two categories.
what is the meling point of spelter?
Spelter, sometimes known as zinc, is used to fuse metals with a higher melting point. The actual melting point of spelter is 787.15 degrees Fahrenheit.
Does a metal burn when it gets higher than its melting point?
No. Metals do not burn, only melt.
Do have nonmetals have high melting points?
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.
Are the trends for melting point and boiling point the same as nonmetals and explain?

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.
What is the melting point for nonmetals?
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).
What properties is not a property of metals?
Low Melting Point. Most metals have high melting point and are solids at room temperature.
