metals
most non ferrous materials are poor conductors with exceptions
A material that allows heat to flow through it easily is known as a conductor. Metals like copper and aluminum are good conductors of heat due to their free-flowing electrons that carry thermal energy efficiently. Conversely, materials like wood or Styrofoam are poor conductors, known as insulators, because they impede the flow of heat.
A group of shiny conductors is called a cluster or a collection of metals that are good conductors of electricity, such as copper, silver, and gold. These metals have high electrical conductivity due to the free movement of electrons within their atomic structure.
The group on the periodic table with the poorest conductors is Group 18, the noble gases. These elements, including helium, neon, argon, krypton, xenon, and radon, are characterized by their complete valence electron shells, which make them chemically inert and non-metallic. As a result, noble gases do not possess free electrons to facilitate electrical conductivity, making them excellent insulators rather than conductors.
High ionization energy and poor electrical conductivity
Group 1 elements, also known as alkali metals, are generally good thermal conductors due to their metallic bonding and free-moving electrons. However, their thermal conductivity is lower compared to other metals like copper or aluminum. While they are capable of conducting heat effectively, their low density and relatively soft nature can limit their practical applications in thermal conduction compared to more robust metals.
Conductors
Group 14 elements such as silicon or germanium generally act as semi-conductors. Boron, a group 13 element, normally acts as a dopant in semiconductors.
all metals are good conductors of heat and electric currents
The poorest conductors of electricity in the periodic table are found in Group 18, the noble gases, and Group 14, particularly the nonmetals like carbon in its diamond form. Noble gases have completely filled electron shells, making them very stable and unreactive, thus not conducting electricity. Additionally, nonmetals generally lack free electrons, which are essential for electrical conduction. Overall, these groups exhibit minimal electrical conductivity compared to metals.
