Gold, silver, copper.
The element you are referring to is likely gold. Gold is a shiny and malleable metal, but it is a poor conductor of electricity compared to other metals like copper or silver.
No- hydrogen is a gas at room temperature.
No, the element sulfur (S) is not shiny and is not a good conductor of heat. Sulfur is a non-metal and is typically a yellow, brittle solid at room temperature. It is a poor conductor of heat due to its molecular structure, which does not allow for efficient transfer of thermal energy.
Based on the properties you described, the unknown element is likely a metal. Metals are typically shiny and good conductors of electricity. You could also predict that it is likely malleable and ductile, as these are common properties of metals.
The element that is shiny and a good conductor of heat and electricity is copper. Copper is widely used in electrical wiring, electronics, and plumbing due to its excellent conductivity properties.
a metal
The element that fits this description is silver (Ag). Silver is a shiny metal that is an excellent conductor of both electricity and heat.
One element that fits this description is platinum. Platinum is a dense, shiny metal that is solid at room temperature. It is known for its lustrous appearance and high density.
Copper, for example. Basically all metals.
The element that generally has a shiny luster and is a good conductor of heat and electricity is metal, particularly metals like copper, silver, and gold. These metals have free-flowing electrons that allow them to conduct electricity and heat efficiently, and their shiny surfaces result from their ability to reflect light.
Yes, this is mostly true. It starts to become untrue near silicon.
