Chromium is used to coat steel and plastic with a chrome finish.
Chromium
Silver is a shiny metallic gray (the element gave rise to the descriptive name of the color silver).
No; think of carbon. This is a non-metallic element; it exists in the forms of diamond and graphite - both "shiny" substances.
Thallium is a soft, metallic element with a texture that is smooth and somewhat shiny when freshly cut.
Chrome is a metallic element, a transition metal with a shiny surface. It is commonly used in metal alloys and has a high melting point.
Every metal on the periodic table has a silver color.
Magnesium is a solid at room temperature. It is a metallic element with a shiny, silver-white appearance.
Iodine is a non-metallic element that is a dark grey to shiny black, lustrous solid at room temperature.
It is metal as it conducts electricity and it is on the left side of that big black line in the periodic table. It is in fact used in wires for it's conductive properties.
An example of an element that is not shiny and does not conduct heat and electricity well is sulfur. Sulfur is a brittle, non-metallic element that typically appears as a yellow solid. It is poor in terms of electrical and thermal conductivity, making it a good insulator. This property, along with its dull appearance, distinguishes sulfur from many metallic elements.
Chromium is not a rock, but rather a mineral. It is also a chemical element that is metallic and shiny.
Metallic elements are usually shiny.
platinum is a metal because it is shiny but it can be a metalloid or transition metal
