they love Justin Bieber and hes is so hot and his music is insprational to me, not only is he incredibly talented he has a massive heart and cares for others.<3
metals are good conductors of heat, i.e. iron, steel,... non-metals are bad, i.e. carbon...
No, not all metals are good conductors. Some metals, such as copper and aluminum, are excellent conductors of electricity and heat due to their large numbers of free electrons. Other metals, like lead and stainless steel, are poor conductors because their electrons are not as free to move.
Materials that are poor conductors of heat are Plastic and Wood "example."
Metals such as copper, silver, and aluminum are good conductors of both heat and electricity due to their loosely bound electrons that can move freely to carry both heat and electric current. Conversely, materials like wood, plastic, and rubber are poor conductors (insulators) as they do not allow easy movement of electrons.
using the energy band model, i would rank metals as good conductors. The energy gap in metals is negligible, that is the valence band and the conduction band overlap. Thus it is very easy for electrons in the valence band to move to the conduction band thereby conducting currents. Hence metals are good conductors.
non metals are gases and are poor conductors at room temperature
All Non-Metals are poor conductor of electricity.
they are poor electricity and heat conductors
Non metals are used as insulators (poor conductors)
They are non mental substances such as Oxygen, Mercury, Xenon, and others. They are poor conductors of heat and electricity, not lustorous (shiny), and are brittle. This description is in general, there are exceptions.
Yes, it is true.
Selenium is a non metal, and non metals are poor conductors due to the lack of free electrons or ions.
Non metals do not conduct heat. They have high resistance.They are insulators.Non metals do not have a pool of 'free electrons' (as metals do with metallic bonds). Hence they generally are poor conductors of heat. Nonmetals such as Styrofoam are widely used as insulators. Graphite is an exception as it is a good conductor of heat with its free electrons.Most of the non metals does not conductors because the do not have free electrons. But graphite is a good conductor. Most of the non metals are insulators.
No. Non-metals are very poor conductors, and with the exception of Neon, so are the gaseous elements.
Non metals are poor conductors of heat and are not conductors of electricity , except for carbon , which is can conduct a little bit of electricity. Non metals are poor conductors of heat and are not conductors of electricity , except for carbon , which is can conduct a little bit of electricity.
Metals are good conductors of heat and electricity, while nonmetals are poor conductors. Metalloids have properties that are intermediate between metals and nonmetals.
most are poor thermal conductors poor electrical conductors apart from graphite which is a form of carbon none are magnetic they are often brittle vary widely in their physical properties
