What else can I help you with?
Is radium bendable?
No, radium is a hard and brittle metal that cannot be bent easily.
Charge carriers in a metal are electrons rather than protons because electrons are?
Charge carriers in a metal are electrons rather than protons because electrons are negatively charged and much lighter, allowing them to move more easily through the metal lattice in response to an applied voltage. Protons are held tightly within the nucleus of atoms and cannot move freely to conduct electricity.
Which can be cut with a knife chromium or dysprosium?
Chromium can be cut with a knife because it is a relatively soft metal. Dysprosium, on the other hand, is a hard and dense metal that cannot be easily cut with a knife.
What is the bond type for a metal plus non metal?
The bond type formed between a metal and a non-metal is typically an ionic bond. In this bond, the metal atom donates one or more electrons to the non-metal atom, resulting in the formation of positively charged metal cations and negatively charged non-metal anions. The electrostatic attraction between these oppositely charged ions holds them together, creating a stable ionic compound.
Is it true that in chemical reactions metal atoms usually become positively charged ions?
Yes, in chemical reactions, metal atoms tend to lose electrons to form positively charged metal ions. This is because metals have low ionization energies, making it easier for them to lose electrons and achieve a stable electron configuration.
How is an electroscope is charged by friction?
An electroscope can be charged by friction through the process of rubbing a charged object, such as a glass rod or a piece of fur, against the top metal cap of the electroscope. This transfers some of the charge from the object to the electroscope, causing a redistribution of charges within the electroscope's metal leaves.
If you rub a coin briskly between your fingersit will not seem to become charged by frictionwhy?
because coin is made up of insulated metal thats why coin cannot charged
Why only one end of metal rod cannot be charged?
Metal is a good conductor. Any charge will quickly be distributed over the entire metal piece.
Is radium bendable?
No, radium is a hard and brittle metal that cannot be bent easily.
Would a negatively charged balloon stick to a metal wall as easily as to a wooden wall?
No, a negatively charged balloon would stick more easily to a metal wall compared to a wooden wall due to the higher conductivity of metals. The charges on the balloon induce opposite charges on the metal surface, creating a stronger attractive force.
Will rubbing a metal rod and silk produce an electrostatic charge?
Yes, rubbing a metal rod with silk can produce an electrostatic charge due to the transfer of electrons between the two materials. This friction creates a separation of charges, with the metal rod becoming positively charged and the silk becoming negatively charged.
Why does coating surfaces with oil reduce friction?
Coating surfaces with oil reduces friction by creating a lubricating layer between the two surfaces in contact, which helps to reduce direct metal-to-metal contact and friction. This lubricating layer allows surfaces to slide past each other more easily, resulting in lower friction and wear on the surfaces.
Why does lubrication increase friction?
Lubrication does not increase friction; it actually reduces friction between moving surfaces by creating a barrier that allows them to slide past each other more easily. The lubricant helps to smooth out any imperfections on the surfaces, reducing the resistance and wear that can occur from direct metal-to-metal contact.
How does oil reduce air friction?
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
Why do we say that in metal conductors, electrons move but protons don't?
In metal conductors, electrons move because they are negatively charged particles that can flow freely. Protons, on the other hand, are positively charged particles that are tightly bound within the nucleus of an atom and do not move easily in a conductor.
Do metal objects get charged by conduction?
Yes, metal objects can become charged by conduction if they come into contact with a charged object. If a charged object is connected to a metal object, the excess charge can flow through the metal by conduction, causing the metal object to become charged.
Why can't a non conducting material be charged easily by rubbing?
I don't think there is such a thing as a "non-conducting metal". All metals are good conductors.
