An ionic bond exists when one element donates its electrons to the other element in the bond. It is not a true bond but rather an electrostatic attraction (the + of one is attracted to the - of the other) Ionic bonds occur if there is a great difference in electronegativity (greater than 1.7 in the pauling scale). Usually they will occur with a alkaline metal (1A element - very low electronegativity) and a halogen (7A - very electronegative.) Some properties are that they disassociate in water (depressing the freezing point raising the boiling point and making the liquid conductive). They form crystal complexes and do not truly exist as a molecule rather as an ionic solid with no definable beginning or end. They therefore do not have a molecular formula but rather just an empirical formula representing their ratio.
list three physical properties associated with an ionic bond
Three physical properties associated with an ionic bond are: melting point, boiling point, and hardness.
These are melting point, boiling point, hardness.
A few physical properties of an iron nail are its mass, volume, and density.
Very much higher.
extended solids are high pressure phases whose properties are enhanced by the formation of high strength covalent bonds
Since characteristic properties for a given substance never change, they can be used to identify unknown matter.
Carbon nanotubes are actually just your everyday normal carbon atoms that are rolled in tubes. It's the atomic structure, not the chemical properties, that give it it's bulletproof strength.
These are melting point, boiling point, hardness.
The 5 physical properties are: 1. Mass 2. Strength 3. Ductility 4. Conductivity 5. Temperature stability
1) Aggregation of the molecular chains to form elementary crystals and fibrils. 2) mechanical strength
A metallurgist studies both the chemical and physical properties of steel, including its tendency to rust and its strength. Hope that helped!
No. Physical properties would include: tensile strength, thermal and electric conductivity, colour, crystalline form, ductability, density, Chemical properties would include: electro-negativity, valance, activation energy,
Its texture, its strength, its flexibility, its melting and boiling points, it elasticity (bouncy-ness)...
Rubber performance can be divided into two categories, structural properties, and functional properties, structural properties refer to high elasticity and strength and other mechanical properties;Functional properties refer to the physical and chemical properties of rubber, such as dielectric resistance, electrical insulation, chemical resistance, etc.
Physical properties are the 'Measurable properties which describe the physical system's state', such as Density, Fusibility etc. Whilst 'Mechanical Properties' as it says in Collins CDT Design and Realisation book Pg 39, that a Mechanical property is a property which is the behaviour of the material when its linked to the application of force such as Strength.
physical properties are properties that can ONLY ne observed by changing the chemical identidy of the substance. example: ph,flammibility, wether it dissolves or not,how it reacts to water... physical properties are properties that can be observed without having to change the substance. example: smoothness, wetness, its color ,its smell ,its texture...hope it helped ----------------------------------------------- Physical properties: density, color, hardness, electrical conductivity, thermal conductivity, viscosity, tensile strength, malleability, magnetic properties, refractive index, etc. Chemical properties: reactivity, solubility, aptitude to thermal degradation, toxicologic properties, valences, heat of combustion, enthapy of formation, flammability, bonding type, oxydation reactions, etc.
One cannot design any machine or structure properly without knowledge of the material physical properties of the materials. Key properties are strength, density, modulus, thermal expansion, and conductivity.
Strength is a physical (mechanical) property of materials.
the collagen fibers of bone have great tensile strength(the strength to endure stretching forces), while the calcium salts, which are similar in physical properties to marble, have great compressional strength (the strength to endure squeezing forces)
