No, coal is very rough. It is black and rough. Sometimes it sparkles, but I do not think it is shiny.
"metallic" is the name for a luster. It means it looks shiny like polished metal.
It is not metallic because it does not have a shiny luster, does not conduct electricity, and is not malleable. (you can't bent it like tin foil)
Metal has a metallic luster and is a conductor.
platinum is a metal because it is shiny but it can be a metalloid or transition metal
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.
Metallic usually refers to a finish (paint, trim), meaning it looks(shiny/ highly reflective)or contains metal (old metallic paint had metal flake in it to give a glitter effect.)
The substance that don't have metallic luster means that they do not have metallic properties. The shiny luster is what will mostly indicate the presence of a metal.
The lustre of a metal is how shiny the metal is.There are two different types of lustre. One is metallic lustre, which is like the shininess of a polished metal surface. The other is non-metallic lustre, which is the opposite of metallic lustre, but is still shiny
Antimony is a metalloid which means that it has metallic and nonmetallic properties and it is element 51 in the Periodic Table lying in the diagonal metalloids in the p group. The metallic and nonmetallic properties may be, for example, that it is grey and shiny like a metal but it may also be brittle and not conduct heat and electricity like a nonmetal.
Selenium has no metallic propeties, it isn't shiny, an electrical conductor etc. It forms anions, Se2-.
No; think of carbon. This is a non-metallic element; it exists in the forms of diamond and graphite - both "shiny" substances.
