Most metals are conductors. A semiconductor is a non-metal material like silicon or germanium which is'doped' with another substance to give the material either a surplus of outer-shell electrons, or a deficiency of them.
Metal is a good conductor of electricity due to the presence of free electrons, while semiconductor has conductivity in between metal and insulator and its conductivity can be controlled by doping. Insulator has very low conductivity as it lacks free electrons for conduction.
Silicon is a semiconductor. It is widely used in electronic devices due to its semiconducting properties, which allow it to be either a conductor or an insulator depending on the conditions. Silicon is not classified as an alkali metal, alkaline-earth metal, or transition metal.
A geranium is a flower, and not a semiconductor. The element Germanium, however, is a semiconductor, which means it has an electrical conductivity somewhere between that of a metal and an insulator.
Lead is a metal and is considered a good conductor of electricity. It is not a semiconductor or insulator.
This solid is a semiconductor.
No, tungsten is not a semiconductor. Tungsten is a metal known for its high melting point and resistance to corrosion. Semiconductors are materials that have conductivity between that of a conductor and an insulator, like silicon or germanium.

No, phosphorus is not an insulator. It is a semiconductor, which means it has electrical conductivity in between that of a conductor and an insulator.

Astatine is not a good conductor of heat or electricity. It is a semiconductor, meaning it has properties between those of a metal and an insulator.
Its an Insulator
Germanium is a semiconductor
