What else can I help you with?
Do the halogens have a high or low melting points?
They have low melting points and high reactivity.
Do simple molecular substances have high or low melting and boiling points?
Simple molecular substances typically have low melting and boiling points. This is because the weak intermolecular forces, such as London dispersion forces, in simple molecular substances are easily overcome compared to the stronger bonds in ionic or metallic substances.
Sulfur oxygen an phosphorus are examples of what?
Sulfur, oxygen, and phosphorus are examples of nonmetals. These elements typically exhibit properties such as low melting points, poor conductivity of heat and electricity, and a tendency to gain electrons in chemical reactions.
What are very soft shiny metals with low melting points?
Some very soft shiny metals with low melting points include mercury, gallium, and cesium. These metals are considered to be soft because of their low hardness and can easily be cut with a knife. Their low melting points make them suitable for various applications such as thermometers, liquid metal coolants, and some types of batteries.
What do oxygen neon and argon have in common?
Oxygen, neon, and argon are all noble gases found in the periodic table. They are all odorless, colorless, and non-flammable. These gases are also chemically inert and have low boiling and melting points.
Do nitrogen and oxygen have very high melting points?
No, they have very low melting.
Do the halogens have a high or low melting points?
They have low melting points and high reactivity.
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.
How do you separate oxygen from methane?
Oxygen can be separated from methane through a process called fractional distillation. The mixture of oxygen and methane is cooled to extremely low temperatures, causing them to condense into liquids. Since oxygen has a lower boiling point than methane, it can be separated by evaporating off the methane first.
Do salts have very low melting points?
No
Silvery solids with low densities and low melting points found in group 1?
These are alkali metals, such as lithium, sodium, and potassium. They have low densities and low melting points relative to other metals due to their atomic structure and metallic bonding. They are highly reactive and must be stored in oil to prevent reactions with moisture or oxygen in the air.
Does non metals have low melting points?
Yes.
Do solids have a high or low melting point?
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.
Do group one metals have a high melting point?
No. Group 1 metals (commonly called the alkali metals) have low melting points.
Why do molecular compounds have low melting points and low boiling points relative ionic substances?
The bonds in the molecule are weaker.
List properties common to many organic compounds?
Some common properties of organic compounds include having covalent bonds, containing carbon and hydrogen atoms, being flammable, having low melting and boiling points, and often having a complex molecular structure.
Are the elements in the boron group high-melting?
It varies. Boron and thallium both have relatively high melting points while gallium and indium have very low melting points.
