What is a better conductor. iron or carbon?
Iron has a atomic no. of 26 and carbon has an atomic no. of 12. No. of electrons in any atom= Atomic no. of the element. Therefore, we can say that iron has more no. of electrons.
Is water a better conductor than plastic?
No, water is not a better conductor of electricity than silver.Water can become a better conductor in acidic medium(by decreasing its pH). But it may split up into Hydrogen & Oxygen.
How does a valence electrons in a metal moves?
The characteristic that allows some metals to be better conductors of electricity is that they have 'free electrons'. Free Electrons simply means that there is a weaker bond between the electrons on the outer valence shell to the nucleus of the atom, than other atoms. This weak bond allows electrons in metals to become more easily excited (when mechanical means of generation occurs), where the electrons are able to transfer from one atom to another.I imagine this is what the question is asking. Basically, electricity is inherent in the material. Metals have weak bonds in their outer valence electron shell.A: In metals, the atoms move freely, allowing heat to travel faster. :)
What allows valence elections in metals to move throughout the metal?
metal atoms being so close to one another that their outermost level overlap. Cause of the overlapping metallic bonds extend throughout the metal in all direction, so valence electrons can move throughout the metal.
Why graphite is a better conductor than diamond?
Graphite is a better conductor than diamond because graphite has delocalized electrons in its structure that can move freely along its layers, allowing for better electrical conductivity. In contrast, diamond has a tightly bound structure with no free electrons, leading to poor electrical conductivity.
What makes copper and aluminum conductive?
The outer electron shell of an atom is called the valence shell. The electrons in the valence shell are called valence electrons. The valence electrons of most metals are not very well bound to the atom making them good conductors. The kinetic energy of the valence electrons of an element is determined by the amount of valence electrons (less is better, one is optimal) and the distance of the valence electrons from the nucleus. Example: Silver is the best metallic conductor, it has five shells with one electron in it's outer shell, copper has four shells with one electron in it's outer shell. Silver's fifth shell is further away from the nucleus than copper's fourth shell making silver a better conductor even though they both have one valence electron.
Is sodium a better electrical conductor than francium?
Yes, sodium is a better electrical conductor than francium. This is because sodium has one valence electron that can easily move and carry electrical charge, whereas francium has only one valence electron that is trapped in an inner shell by its atomic structure, making it less available for electrical conduction.
How many additional valence electrons does fluorine need to have a full valence?
I believe you are talking about fluorine. If you are, F needs one more electron to gain a full shell.If you go to WikiAnswers for this information, that is counterproductive, because there is a much better way to do it. Look at the periodic table. Groups IA through VIIIA tell you what you need to know. IA has one valence electron, IIA has two valence electrons etc. Fluorine is in group VIIA and therefore has seven valence electrons. All atoms want eight, and thus fluorine is in need of one more.
Why is sodium a better conductor than francium?
Sodium is a better conductor than francium because sodium has one valence electron that is easily released for conducting electricity, whereas francium's larger atomic size and placement in a lower period make it less efficient at transferring electrons. Additionally, francium's high reactivity and rarity in nature also hinder its usability as a conductor compared to sodium.
Why is a metal with three outer electrons a better conductor that a metal with one outer electron?
Because an electric current is basically electrons moving along, so if there are more slightly freer electrons there wil be a greater facility for electron movement.
What are some conductor of electricity?
In general, the best conductors of electricity are metals, which share their valence electrons loosely; thus, allowing them to move freely. Usually, the fewer valence electrons (electrons in the outermost orbit), the better the conductor. But, there are some exceptions, such as: aluminum (has 3 valence electrons) is a better conductor than platinum (has only 1 valence electron). Silver is the best conductor; however, it's very expensive, so copper or aluminum are used in most wiring applications. Gold is not as good a conductor (Higher resistivity) as either Copper or Silver, but is less prone to corrosion, and so is used in hostile enviromnets, or for connectors; as well, but it has a relatively low melting point, giving it a tendency to melt. A good non-metal conductor is carbon, but only when it's in the form of graphite. Tap water is another good, non-metal conductor. It's worth remembering that the Manhattan Project, which ran during World War II, needed the best possible conductors for the magnetic cores they were designing. So, they requisitioned several TONS of silver from the US Treasury for the war effort.
What is a better conductor. iron or carbon?
Iron has a atomic no. of 26 and carbon has an atomic no. of 12. No. of electrons in any atom= Atomic no. of the element. Therefore, we can say that iron has more no. of electrons.
How do the valence electrons tell about the reactions of different elements?
Not sure if I understand your question correctly, but some elements are more electronegative than others, so they draw in electrons better than others. For example, in NaCl, chlorine (Cl) is much more electronegative than sodium (Na) so it simply takes the sodium's extra valence electron.
What is a better conductor of electricity copper or gold?
Copper is a better conductor of electricity than gold. This is because copper has more free electrons available for conducting electricity due to its electron configuration. Gold has fewer free electrons, making it less conductive than copper.
What makes a better conductor copper or iron?
Copper is better conductor than iron because copper has higher electron affinity of 1.22948 eV than iron which is 0.16299 eV.
Why are metals electrically conductive?
The electrons in their valence band are so loosely bound that in the bulk material they form an "electron gas" that fills the material and can freely flow in response to voltage placed across that material.
How many valence shell electrons are there in semiconductor atoms?
Silicon, the most widely used semiconductor, has four valence electrons. This places it in between the conductive metals, which have one to three valence electrons, and the non-conductive non-metals which have five to eight valence electrons.
