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.
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.
Mercury is the only element that is both liquid at room temperature and a good conductor of electricity. Mercury also has the other properties specified.
Yes, this is mostly true. It starts to become untrue near silicon.

Gold, silver, copper.
Samarium is a good conductor for heat and electricity.
At standard temperature and pressure (STP), the element that is malleable and a good conductor of electricity is copper.

Silver is a shiny element that is a good conductor of both thermal energy and electric current. It has the highest electrical conductivity of any metal, making it highly effective for conducting electricity. Additionally, silver also has a high thermal conductivity, allowing it to efficiently transfer heat.
Metals are associated with being shiny and good conductors of electricity. They are typically not dull, brittle, or poor conductors of electricity.
ice
One example of an element that is not a good conductor and a good insulator is sulfur. Sulfur is a non-metallic element that is a poor conductor of electricity due to its lack of free electrons for easy electron flow. However, sulfur is a good insulator because its atoms are tightly bonded together, making it difficult for electricity to pass through.
