Using two different metals creates a potential difference or voltage between them, which allows the flow of electrons to generate an electric current. This process is known as the Seebeck effect in thermoelectricity and is utilized in devices such as thermocouples to measure temperature differentials.
Yes, most alloys are good conductors of heat and electricity. This is because alloys are made by mixing different metals together, which creates a structure that allows the flow of heat and electric charge more easily compared to pure metals.
No single piece of metal will produce electricity when heated. You will need two different metals, mechanically touching. When the join between the metals is heated, it will produce electricity, dependant on the metals used. This is known as a 'thermocouple'.
Metalloids have properties that are intermediate between metals and nonmetals. They can conduct electricity to some extent, but not as well as metals. Metalloids are often semiconductors and have properties that make them useful in electronic applications.
Steel, iron, copper, aluminum and all other metals conduct electricity very well compared to most other compounds. With the discoveries in solid state physics of the 20th century we learned that metals are collections of atoms which have somewhat unusually properties of the electrons. In metals the outermost electron (sometimes two) is not specifically associated with that one atom but is free to associate with atoms far and wide. We say these are delocalized electrons. Since the electrons are not attached to specific atoms, it takes very little energy to move them. As a result, any small voltage causes electron flow in a metal. This movement or flow of electrons is called electricity so this is why metals conduct electricity. Aside: Metals are not the only materials that conduct electricity, they just do it especially well.
The Canadian Toonie coin, which is a two-dollar coin, is made of two different metals - an outer ring of nickel and the inner core of aluminum-bronze. The aluminum-bronze core allows the coin to conduct electricity.

Mercury and bismuth are two metals that do not conduct electricity. Mercury is a liquid at room temperature and bismuth has a high electrical resistance, which restricts its ability to conduct electricity effectively.
Astatine is not a good conductor of electricity. This is because it is a non-metal. All non-metals do not conduct electricity, and all metals do. The two exceptions are carbon and silicon, which are non-metals, but conduct electricity well.
Metals and Nonmetals have specific characteristics. Two characteristics of Nonmetals are typically brittle and do not shape easily, and they do not conduct heat or electricity well.
Group 1 and Group 2 metals conduct electricity because they have only one or two electrons in their outermost energy level, making it easy for these electrons to move and carry an electric current. The presence of these loosely held electrons allows them to easily flow in response to an electric field.
Yes, most alloys are good conductors of heat and electricity. This is because alloys are made by mixing different metals together, which creates a structure that allows the flow of heat and electric charge more easily compared to pure metals.
Tin is a good conductor of heat and electricity because it has high thermal and electrical conductivity properties due to its atomic structure. The free-flowing electrons in the tin lattice allow for easy movement of heat and electricity through the material.

Because covalent bonds are between elements without metallic properties, and in order for a bond to conduct electricity, the bond has to include two metals, AKA a metallic bond.
Non-metals like graphite and doped silicon can conduct electricity due to the presence of free electrons that allow for electron movement. However, most non-metals are poor conductors of electricity as they lack the free electrons needed for conduction.
