What are shiny metals?
Transition Metals are what we usually think of when we think of metals.
They are hard and shiny, strong, and easy to shape.
They are used for many industrial purposes.
This group includes iron, gold, silver, chromium, nickel, and copper, some of which are also noble metals..
Is shiny surface metal or nonmetal?
The periodic table on the left separates elements into three groups: the metals (green in the table), nonmetals (orange), and metalloids (blue). Most elements are metals. They are usually shiny, very dense, and only melt at high temperatures. Their shape can be easily changed into thin wires or sheets without breaking.

Why is metal shiny?
The electrons that are farthest from the nucleus give a metal its shine. Light reflects, or bounces off, these outer electrons. This makes the metal appear shiny. This shiny appearance on the surface of some metals is called luster.
Which metal is not shiny?
pottasiumpottasium is metal which does not shining surface .
Can a mirror be called Metal why why not?
Answer: Mirror is a reflective surface made up of glass with its one face painted with any shiny metal usually mercury. This doesn’t make any mirror a metal.
Why is silver shiny?
Many different kinds of metal are shiny. Gold is a metal which stays shiny for a long time because it does not react much chemically with the air. Silver is shinier, but tarnishes easily. … When a light wave hits a metallic surface, the electrons on the surface are pushed and pulled by the field of the incoming wave.
Is oxygen a metal or nonmetal?
Oxygen, carbon, sulfur and chlorine are examples of non-metal elements. Non-metals have properties in common.
Is Silicon shiny or dull?
Metalloids are solids that can be shiny or dull. They conduct electricity and heat better than nonmetals but not as well as metals. Silicon for example has a shiny metallic luster and is a medium conductor BUT it is brittle and shatters when you hit it with a hammer.

Are all metals shiny?
All metals except for mercury are solids at room temperature. Many metals are shiny, ductile, and malleable. Most are also good conductors of heat.
Is iodine shiny or dull?
Iodine is a non-metallic, dark-gray/purple-black, lustrous, solid element. Iodine is the most electropositive halogen and the least reactive of the halogens even if it can still form compounds with many elements. Iodine sublime easily on heating to give a purple vapour.
Why are metals so hard?
Metal have lots of free electrons which create a huge electron pressure (on the order of 100,000 atm), so to crush them,pressures higher than their internal electron gas pressure is required; this is why they are hard.
Is Selenium dull or shiny?
Selenium is a nutritionally essential element. … The most stable form of the element, crystalline hexagonal selenium, is a metallic gray, while crystalline monoclinic selenium is a deep red.
Is lead shiny or dull?
Lead is a shiny, gray-blue poor metal. It gets tarnished easily to a dull gray color. It is soft and malleable. It is very shiny when it is melted.
Is magnesium shiny or dull?
Magnesium is a shiny, silver or gray colored metal that is light in weight and strong. Th density of magnesium is 1.738 g/mL, which means the metal will sink in water, but it is still relatively light weight. Chemical Properties: Magnesium is a silvery white metal.
Can a mirror be called Metal?
Answer: Mirror is a non metal. Explanation: Glass is an amorphous silica form, so it’s not metal, but you’ll be excited to know it’s either solid or liquid.
Is gold shiny or dull?
