Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.

What is neon's melting and boiling point?
The boiling point of Neon is -246.048 º C The melting point of Neon is -248.67 º C
Do nonmetals have higher melting points or lower boiling points?
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.
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.
When is metal not a metal?
Metals have luster ,they are electric and heat conductors , moreover they have high melting and boiling points.This properties will distinguish it from nonmetals.
What are metals on the periodic table and how do their properties differ from nonmetals and metalloids?
Metals on the periodic table are elements that are typically shiny, malleable, and good conductors of heat and electricity. Their properties differ from nonmetals and metalloids in that metals tend to be more ductile, have higher melting and boiling points, and are more reactive. Nonmetals, on the other hand, are typically brittle, poor conductors of heat and electricity, and have lower melting and boiling points. Metalloids have properties that are intermediate between metals and nonmetals.
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.
Will there be effect on melting or boiling point of a substance if another substance is added to it?
Yes, impurities have important effects on the melting and boiling point of materials.
Are melting and boiling point physical properties of a substance?
Yes, melting and boiling points are physical properties of a substance. They represent specific temperatures at which a substance transitions from one phase to another - solid to liquid for melting point, and liquid to gas for boiling point.
What are properties of nonmetal?
Nonmetals tend to have lower melting and boiling points than metals. They tend to be dull and brittle. They do not conduct heat or electricity. They are insulators.
How are solid nonmetals different from metals?
Solid nonmetals tend to be brittle, have lower melting/boiling points, and are poor conductors of heat and electricity. Metals, on the other hand, are generally malleable, have higher melting/boiling points, and are good conductors of heat and electricity.
Which of the following is a characteristic of nonmetals?
- lower density- lower hardness- lower melting point- lower boiling point- some nonmetals are gaseous or liquidsetc.
What are the properties for an ionic bond?
Ionic bonds form between atoms with large differences in electronegativity, resulting in the transfer of electrons from one atom to another. These bonds are typically formed between metals and nonmetals. They are characterized by high melting and boiling points, as well as the tendency to dissociate into ions in a polar solvent.
Does melting and boiling cause physical changes?
Melting and boiling are physical changes.
