Which statement best answers the question, "Why is copper a good conductor of electricity?"?AnswerA.Copper atoms have a loosely held electron in their outer shell that is able to move freely to other atoms.b.Copper atoms are tightly bound and are able to work with other copper atoms to exchange electrical charges.C.Copper has an equal number of protons and electrons making the flow of current possible.D.Copper's outer shell electrons are not balanced and must join with other copper atoms in order to be stable.I know it's either A or B I just don't know which one. Please help?
Copper is a ductile, semi-precious metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. The major applications of copper are in electrical wires (60%), roofing and plumbing (20%) and industrial machinery (15%). Copper is mostly used as a metal, but when a higher hardness is required it is combined with other elements to make an alloy (5% of total use) such as brass and bronze. A small part of copper supply is used in production of compounds for nutritional supplements and fungicides in agriculture. Machining of copper is possible, although it is usually necessary to use an alloy for intricate parts to get good machinability characteristics. The atomic number of copper is 29, which means it has 29 protons in the middle and 29 electrons moving around the outside. (The 29 negative charges of the electrons and the 29 positive charges of the protons balance out, so the atom is neutral when all of its electrons are in place.) Copper has two electrons in the innermost shell, eight in the next shell, eighteen in the third shell, and one in the fourth shell. This means that the first three shells each have as many electrons as they can hold, and the fourth shell has one lonely electron. (The fourth shell can hold up to 32 electrons.) Because this one lonely electron is all by itself in the outer shell, it can easily separate from the rest of the atom and go roaming around, which makes copper a very good conductor.
I'm having troube finding uses of Copper for a Science report in school.
Copper is good conductor of heat -can be used for cooking utensils -electric field like wiring, motor rotors,
i updated my electric box it is ground with a copper wire going outside and to the water meter can i reroute my ground wire to either one thanks
in pa the meter needs grounded on both sides i did mine on the adapters, and ground rods outside
i am doing my science coursework about should we recycle copper from mobile phones. which one is better recycling or mining copper and why?can you answer the question plz and can you give me some links to this question. much appreciated.
just about all metals are heavily recycled. the main earnings is decreased value (much less value than making virgin steel by way of digging ore out of the floor). uncertain that's a downside precisely... one reason some Cu isn't recycled to make greater Cu is that there is too little of it interior the element it is thrown away. occasion must be an previous toaster which has some tiny Cu wires in it yet different the scrap toaster is steel. The steel is recycled to make greater steel however the Cu is going alongside only as an impurity.
Having problems with the a/c, and we know for sure this connection needs to be bonded. What can we use?Thanks!
a shark bite fitiing will let you couple copper to pvc.
A slab of copper of thickness b is thrust into aparallel-plate capacitor of plate area Aand plate separation d; theslab is exactly halfway between the plates. (a) What is thecapacitance after the slab is introduced? (b) If a potentialdifference V is maintained between the plates, what isthe ratio of the stored energy before to that after the slab isinserted? (c) How much work is done on the slab as it isinserted? (d) Is the slab sucked in or must it be pushed in?Copper is a kind of metal. What is its dielectric constant?

what gives copper the ability to be stretched into wires? and what gives copper the ability to be malleable? and what gives copper the ability to be a great conductor of electricity?
Ductility Of Copper
I‘d like to make this statue out of copper pipes. I have one big pipe, and then a bunch of soft copper tubes used for plumbing. I have a soldering iron, and solder-I have been trying to attach some of the softer tubes to the larger one, but the solder snaps right off. with little effortor slides right off before it cools-im having trouble getting it to stick to the copper? Any suggestions?? thank you!
My Audi has it. If you live in the northeast, it is WELL worth the money. In a warm/dry climate it is only worht it if you car has 500 hp or something crazy.
