Why doesn't water conduct as well as copper?
Water becomes a conductor of electricity that can replace copper in wires when the water is heated. Hydroelectric power plants heat water to run giant turbines that conduct electricity and generate heat. The places being serviced by the hydroelectric power plant still need copper wires, though to have electricity.
What type of structures do metallic bonds create?
Giant crystalline lattices in the solid state. Metallic bonding nvolves delocalisation of electrons acoss many atoms. Note that molten metals also conduct electricity- the metallic bonds persist in the molten state.
Is the earth also like a giant battery?
No. Electricity pylons (usually called "transmission towers" in the US) are basically just supports for the wires. They are specifically designed to be insulated from the electricity flowing through the wires.
Is using electricity damaging your environment?
No not unless you redirect it into a giant electro magnet or any sort of electrical dooms-day device.
Describe General trend in physical appearance of the elements in period 3?
Sodium, magnesium and aluminum are all good conductors of electricity. Silicon is a semiconductor.Sodium, magnesium and aluminum all have metallic structures, which accounts for their electrical conductivity and relatively high melting and boiling points.The nuclei of the atoms gets more positively charged.Melting and boiling points rise across the three metalsSilicon has the highest melting point.Phosphorus, sulphur, chlorine and argon are simple molecular substances with only van der Waals attractions between the molecules. Their melting or boiling points will be lower than those of the first four members of the period which have giant structures.These four substance with simple molecular structures also do not conduct electricity.
Why do metals giant covalent structures not conduct electricity?
Because there are no free electrons. However, graphite does conduct electricity as there are free electrons.
Can giant covalent structures conduct electricity when molten?
Some do- for example molten silicon conducts like ametal when molten.
Does pottasium iodide conduct electricity?
Potassium iodide is an ionic compound. Ionic compounds in the solid state do not conduct electricity, because the ions are NOT free to move. They are held in a rigid giant crystalline lattice However, when in the liquid state or in solution, the ions are free to move, and hence conducts electricity, because the rigid giant crystalline lattice has broken down.
Do giant covalent bonds conduct electricity when solid?
No, because the molecules are neutral so therefore there are no charged particles to carry a current.
Properties of compounds with giant ionic structures?
High melting point High Boiling point Conducts electricity when molten or dissolved Cant conduct electricity when solid Example Sodium chloride
Does solid lithium bromide conduct electricity?
no. it is an ionic compound which does not conduct electricity as the ions are not free to move around. however when they are in molten or aqueous state, they are able to conduct electricty as the ions disssociate and then will be free to move about freely.
Can MgO conduct electricity in the solid form?
No.MgO has a giant ionic lattice structure with strong covalent bonds.for ionic compounds,they can only conduct electricity in aqueous or molten state because the giant ionic lattice structure had collapsed and ions are free to move about to conduct electricity.but in solid state,the ions will be held in fixed position and thus is unable to conduct electricity:)
What are three properites of an ionic compound?
Both CATIONS (M^([n]+)) and ANIONS (X^([n]-)) are needed. It has a high melting point. It does NOT conduct electricity as a solid, but does conduct electricity, when liquid or in solution. The bonding is ionic (NOT Covalent) Forms a giant crystalline lattice.
Does solid potassium bromide conduct electricity?
No because it's a crystalline ionic solid. However, dissolve some KBr in water and it will conduct electricity nicely, because in solution it's an electrolyte, with lots of little K+ and Br- ions floating around.
Why graphite is soft and greasy and good conductor of electricity?
Unlike most Giant Covalent Structures like diamond that form four covalent bonds, Graphite only forms 3, meaning it has a free electron meaning that graphite can conduct electricity.
What are the gas giant substances?
The gas giant planets are composed mostly of hydrogen, methane, and ammonia.
Is lightning a giant spark caused by static electricity?
no
