How could you use a pith ball electroscope to learn which material holds onto its electrons more strongly?
You could use the pith ball electroscope to test different materials by charging it with the materials and observing the behavior of the pith ball. If the pith ball is deflected more when charged with a particular material, it indicates that the material holds onto its electrons more strongly.
What else can I help you with?
What is an electron trap?
An electron trap is a localized region in a material where electrons can be captured and temporarily held. This could be due to defects in the crystal structure, impurities, or other factors that create an energy level in which electrons can get stuck. Electrons trapped in these regions can affect the material's electronic properties.
How could a n type semiconductor be produced from pure germanium?
To produce an n-type semiconductor, pure germanium can be doped with an appropriate impurity such as phosphorus or arsenic. These impurities introduce extra electrons into the germanium crystal structure, resulting in an excess of negative charge carriers (electrons) and hence an n-type semiconductor material.
Are all materials made up of elements?
Any material that you encounter on earth is made of an element or some combination of elements. An element is just the name of a substance that contains just one type of atom. An atom is just a specific combination of neutrons, protons, and electrons; atoms/elements are defined in the Periodic Table according to their atomic number, which is the number of protons in their nucleus. So every material you encounter is some combination of electrons, protons or neutrons unless you are encountering some very high energy phenomena. A material which is not made of elements could be pure electrons. Although close to impossible to isolate (they repel each other so strongly), pure electrons would not be an element. Electricity in a wire would not count because this is just a wire, with some electrons flowing through it and those electrons make up the elements in the wire. A material which is not made of elements could be a plasma. A plasma from Hydrogen in which all electrons and protons are disassociated may be considered not of an element (although not all plasma's would meet this condition and even then you could still consider this plasma an ionized Hydrogen). Very high energy phenomena, such as those in particle accelerators and the early universe, create fundamental particles and plasmas which are certainly not elements (like a quark-gluon plasma). There is basically no material that you could encounter and live to tell that tale that is not made up of some combination of elements.
At n 1 the total number of electrons that could be found is?
At energy level n=1, the total number of electrons that could be found is 2, as the first energy level can hold a maximum of 2 electrons.
What is the core electrons and valence electrons for Li ion?
Li+ ion has only 2 electrons in its only shell and they could be considered as both core and valence electrons.
You are given two objects made from different materials. How could you use a pith ball electroscope to learn which material holds on to its electrons more strongly?
You can charge each material by rubbing it with a cloth to transfer electrons. Then, bring each material close to the pith ball electroscope without touching it. The material that causes the pith ball to deflect more significantly is the one that holds on to its electrons more strongly.
How could you use a pith ball electroscope to learn which two objects that are made from different materials hold on its electrons more strongly?
You could charge the pith ball electroscope by rubbing the two objects separately and observing which one causes the pith ball to deflect more. The object that causes stronger deflection has electrons with stronger hold, indicating that it holds on to its electrons more strongly compared to the other object.
What makes an object positively or negatively charged?
Step one. Charge the electroscope by the induction method. A rod is used of opposite sign to that required on the electroscope . The rod is brought near to the cap so that the leaf diverges by the amount desired, and the electroscope is momentarily earthed by touching it with a finger. The rod is then removed, leaving the electroscope charged. (If the charged rod used is Benoite this leaves a positively charged electroscope, if a glass rod is used then the result is negatively charged electroscope) Step two Now use the object of unknown charge, A charge of the same kind as that on the electroscope will cause an increase while a charge of the opposite kind will cause a decrease in leaf divergence when the object is brought near to the electroscope. You must bring the object down from a good height, and move it slowly down towards the cap so any change in divergence will not be overlooked before the object becomes to close to the cap. Bringing the object down too quickly and too close to the cap could lead to a false reading. Source(s): A. F. Abott Ordinary Level Physics
The outer electaons are attracted to the nucleus by a force stronger than the inner shell eclectrons?
No. The outer shell (valence) electrons are not attracted towards the nucleus as strongly as are the inner (core) electrons. This is why they could be traded in and out during chemical reactions, while the core electrons normally could not.
What would happen if you touched a knob of positivly charged electroscope with another positivel charged object?
If you touch a positively charged object to a positively charged electroscope, the electroscope may become even more positively charged due to the transfer of additional positive charge. This could result in greater divergence of the leaves of the electroscope, indicating a higher level of positive charge on the electroscope as a result of the contact with the positively charged object.
What happens when charging by rubbing?
Static electricity is the result of creating a charge by rubbing two objects together. The positively charged objected with accepted electrons from the negatively charged item giving it an electric charge.
What ia another word for strongly?
I think you could use "firmly" as an alternative to strongly. Or depending on the use, "soundly" could also be used.
Why cant conductors generate static electricity when rubbed together?
Static electricity causes electrons to move from one material to the other. In an insulator, these electrons can't flow back to equalise the charges, whereas in a conductor they can; so whilst they could conceivably generate static electricity, it would be lost as quickly as it was made.
Why in gold leaf electroscope sides parallel to the gold leaf are tin foils?
The tin foils on the sides of a gold-leaf electroscope help to discharge any excess charge quickly, allowing the gold leaf to return to its neutral position. The tin foils also help shield the gold leaf from any external electric fields that could interfere with the electroscope's measurements.
By looking at a solution could you tell if it could absorb uv strongly?
YES
Electrons free to move throughout a material are associated with a what?
It is metallic bond, because you know yea metallic is metal and meteal collect electric, so it mean it free to move so the electricity pass through the meatal and when u tough it you may die exacly.
