Why do conductors conduct electricity while insulaters don't?
Conductors conduct electricity because most of them are made of metals and metals are good conductors of electricity while insulators are made of rubber and rubber does not conduct electricity. To conduct electricity, the atoms that make up the material, have to have free electrons that can pass a charge on. Metals have these free electrons, whereas insulators do not.
How atoms combine to make a bond?
Atoms combine together to form molecules. In molecules the consitutent atoms are held together by attractive forces. This attractive force which binds the atoms in a molecules is called as bond.
Two atoms that share electrons are held together by what bonds?
Atoms are held together by a few forces, depending on how small you look. Quarks (the sub-atomic particles that make up protons and neutrons) are held together by gluons. Protons and neutrons are held together by the strong nuclear force. The nucleus and electrons are held together by the electromagnetic force.
Why are atoms and compounds held together?
The atoms in compounds are held together by chemical bonds
Why do insulators not conduct electricity?
Simple Answer:The fundamental difference between a conductor and an insulator is that some electrons of the atoms of a conductor are not stuck to specific atoms but are free to move throughout the material. For insulators, the electrons are tightly bound to the specific atoms or in the chemical bonds between atoms. A relatively small force created by the electric field due to an applied voltage produces a tremendous movement of the nearly free electrons in a metal and almost no response at all from tightly bound electrons in an insulator.Longer Answer:For a material to carry electricity, it must contain charge carriers that move.In metals, the outermost electrons of the atoms are not localized on the atoms, but extend far out into the material and are often termed delocalized. This is a way of saying that electrons in metals are essentially free to move throughout the material. As a consequence, little or no energy is required to transport electrons through a metal. Metals are thus good conductors of electricity.Materials that are insulators have electrons that are localized on specific atoms or localized in particular chemical bonds that join atoms. To move an electron from one atom to the next requires some energy to initially dislodge it. On the atomic scale, the electric field to dislodge an electron from one atom and move it to a nearby atom is typically very large for materials that are not metals. As a result, most materials are insulators.Finally, it is worth pointing out that ionic liquids, like salt water, conduct electricity not as moving electrons but as a consequence of the movement of charged atoms, e.g. Na+ and Cl-. Conversely, a solution of sugar does not ionize and the molecules are not charged, so conductivity is nearly zero.Caveat: For the expert, the ultimate quantitative answer to this question requires discussing quantum theory of electrons in solids and band structure and impurities and defects and lattice vibrations.
What is the name given to the three particles that make up atoms?
The three particles that make up atoms are protons, neutrons, and electrons.
Does clothes has electrons?
Yes, clothing can have electrons. Electrons are subatomic particles that make up atoms, and since all matter is made up of atoms, clothing can have electrons within its structure.
What Jumps from atoms to atom make electricity?
electrons
Is a material a good insulator if outer electrons of atoms in the material are free to roam around?
No, a material with outer electrons that are free to move easily is a good conductor of electricity, not a good insulator. Insulators are materials that have tightly bound outer electrons, which do not move easily, leading to limited flow of electricity.
What do shells (energy levels) and valence electrons have to do with atoms combining to make molecules?
Valence electrons form the bonds between atoms in a molecule.
How do atoms interact and create chemical bonds?
Chemical bonds are formed by the sharing or donating of electrons. The electrons that atoms use to make chemical bonds are the outermost electrons, also known as valence electrons.
Why do certain materials make good heat insulators?
Cuz of insufficient presense of electrons in the external shell of such material's atom
