1.00 M AlCl3 solution shows more conductivity due to presence of more charges on ions.
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
Bi shows the element bismuth. Atomic number if Bi is 83.
An element "I.D." is an element's atomic number. An element's atomic number shows how many electrons are in an atom of that element. An element's atomic number also determins their position on the Periodic Table.
Semiconductors
Any material is classified as conductor or insulator. There is no perfect conductor or perfect insulator. If a material exhibits more conductivity it is called a conductor and materials with very low conductivity are called insulators. Materials with moderate conductivity would have medium range resistance to electricity. In practice, though, a material either conducts or it doesn't. 'Moderate' would be determined by what you were comparing it to.
Conductivity - either thermal conductivity, or electrical conductivity.
From Wikipedia: In chemistry, a metal (Greek: Metallo, Μέταλλο) is an element, compound, or alloy characterized by high electrical conductivity. In a metal, atoms readily lose electrons to form positive ions (cations); those ions are surrounded by delocalized electrons, which are responsible for the conductivity. The thus produced solid is held by electrostatic interactions between the ions and the electron cloud, which are called metallic bonds. From me:If an element shows these characteristics, it is a metal. Calcium shows these characteristics. Therefore, Calcium is a metal.
