Why can you see your reflection better in a price of metal if you Polish the surface?
A clean metallic surface appears shiny because it is reflecting light. The interaction is due to the conductivity of the surface of the metal. When surface conditions change, the reflectivity is reduced.
Which phrase best describes a metallic bond?
A metallic bond is one where delocalized valence electrons of the metal are attracted to any of the metal cations. The electrons are delocalized meaning they do not stay with any particular nucleus. The bonds are held together by electrostatic interaction between the delocalized electrons and the positive cations.
Why do metallic objects appear colder than wooden objects on winter night?
As metallic objects are having good heat retention capacity.
Why is difficult to change a metallic conductor which is held with hands?
It is difficult to charge a metallic conductor that is held with hands because the charge generated will be grounded through our bodies.
Which particles constitute current in a metallic conductor?
electrons
What is metallic luster?
Metallic luster is a mineral description, referring the interaction of light with the crystal surface, in this case, the look of shiny metal. Simply, the shininess of a metal.
What are metallic bonds at room temp?
Metallic bond is an electrostatic interaction between the metal ions and a sea of free electrons. Mercury is the only liquid metal, whereas all other metals are solids.
Which solid is the strongest-ionic solids metallic solids covalent solids?
Respectively are Calcium cabonate, Tungsten and Diamond (most probably)
What does metallic bonds form between?
Metallic Bonding occurs between metals. If you are looking for the castlelearning answer were the answer choices were sulfur, copper, fluorine, and carbon, the answer would be copper. Hope this helped:)
Why are metallic minerals harder than nonmetallic ones?
This is not true. The only metallic minerals that are at all common are native gold, silver, copper, and platinum. Gold and silver have Mohs hardness of 2.5, copper 3.0, and platinum 4 to 4.5. That's rather soft. By contrast, non-metallic minerals include quartz, topaz, corundum, and diamond, with Mohs hardness 7, 8, 9, and 10 respectively.
What are the two main types of luster?
Metallic and non-metallic
Properties of metallic bond?
The metallic bond is a delocalised bond with free electrons and also may include some covalent interaction This bonding is the cause of the luster, opacity, electrical conductivity, thermal conductivity, strength, malleability, ductility generally associated with the metals.
Is Copper slag is metallic or non-metallic?
It is a mixture - partially metallic and partially non-metallic
Is neutral oxide metallic or non metallic?
Non-metallic
What colors are available for the BMW M3 E46?

Is halite metallic or non metallic?
The mineral halite is non-metallic.
What is a bond formed by the attraction between positively charged metal ions and the electrons around them?
Metallic Bond .
