A material in which electrons are tightly bound and cannot move freely at room temperature is calleda)conductorsb)superconductorsc)semiconductorsd)insulatorsCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

because degree of freedom is different for every elements and in insulators degree of freedom is very less and it doesnot allow electron to move freely in it or doesn't allow to pass through it

Answer

yaa it's insulator and becz of these bounded electrons insulators are bad conductors

Answer

in insulators electrons are tightly bound so they cannot conduct electricity n heat

Answer

yes..its insulators are bad conductors...thus do not conduct electricity

Answer

d as a material which dont have any free election_ and bound tightly, the material is called to be the insulator.

Answer

Insulators are materials in which electrons are tightly bound and cannot move freely at room temperature. These materials have a high electrical resistance, which means that they do not conduct electricity easily.

Insulators have a completely filled valence band, which is the highest energy band in the material. The valence band is filled with electrons and there are no available energy levels for the electrons to move to. This makes it difficult for them to gain energy and move freely throughout the material.

The tight binding of electrons in insulators is due to the strong electrostatic forces between the electrons and the atoms in the material. These forces hold the electrons in place and prevent them from moving.

Insulators are commonly used as electrical insulators in various applications. They are used to prevent the flow of electricity and to provide insulation between conductors. Examples of insulating materials include rubber, glass, wood, and plastics.

Insulators are also used in the construction of electronic devices and circuits. They are used to separate and insulate different components and to prevent unwanted electrical currents.

In summary, insulators are materials in which electrons are tightly bound and cannot move freely at room temperature. They have a high electrical resistance and do not conduct electricity easily. Insulators are used for electrical insulation and are commonly found in various applications and electronic devices.
