scientific notation hhahahahaha
The properties of simple covalent substances such as chlorine, oxygen and water are that it has low melting and boiling points. This is because the weak intermolecular forces break down easily. Secondly, another property is the simple covalent substances are non-conductive therefore the substances with a simple molecular structure do not conduct electricity. This is because they do not have any free electrons or an overall electric charge.
Ionic and metallic substances both do not have covalent bonds!
Chemical properties are properties that depend on the substances reactions with other substances. Physical properties can be observed without changing the composition of the matter.
Metallic: melting point @ 63, boiling point @ 760, properties: soft, silvery, solid, and conductor as a solid. Covalent: melting point @ -101, boiling point @ -34.6, properties: greenish yellow gas and not a good conductor.
Substances interact with other substances by chemical properties
Its molecular make up is neither completely covalent or ionic but it exhibits properties of both.
They are different!
After the mixing the properties of substances remain unchanged.
Molecular substances can have both polar and nonpolar covalent bonds.
It is impossible that all the properties of two substances will be identically.
Covalent substances are ones that contain only covalent bonds. These can be molecular, e.g. CH4, methane, NH3 ammona, or giant molecules such as diamond and silicon dioxide.
polar, covalent, and ionic substances
Covalent bond does not dissolve in water:)
Diamond, graphite and sand are continuous covalent substances.
well ionic substances are solid at room temperature,they are generally soluble in water ,they have high melting and boiling points,while covalent substances are generally liquid and gases at room temperature,non-polar covalent substances are generally insoluble in water while polar covalent are generally soluble in water
properties of matter that determine how a substance reacts with other substances
The smallest particle of a covalent compound that shows the properties of that compound is a molecule.
both r stable and r bounded by weak Van der Waals forces
Some, but not all, substances do so. Such substances are known as catalysts.
Covalent bonds Covalent bonds
Covalent bonding is formed generally between nonmetals.
They are different.
