Without actually testing the particular metal, it is hard to tell which metal will be a good conductor. The best conductor is silver, the second best is copper, the third best is gold. Looking at the Periodic Table, that is not logical! Carbon has been used for spark plug wires. Silicon will not work for spark plug wires. What is going on? While the periodic table is good for predicting and coming close, it does not always provide the best answer. The periodic table predicted platinum would be the best metal for catalytic converters. Some scientist decided to forget predictions and start testing. He discovered rhodium was far better and far less expensive.
The element that is a good conductor that begins with the letter S is Selenium. Another choice could be Scandium.
is a semi-metal
Gold.
At standard temperature and pressure (STP), the element that is malleable and a good conductor of electricity is copper.
Samarium is a good conductor for heat and electricity.
Copper
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.
Silicon is an element that falls in between being a good conductor and a good insulator. It is a semiconductor which means its conductivity can be modified by introducing impurities or applying an electric field.
Gold.
ice
The element that is shiny and a good conductor of heat and electricity is copper. Copper is widely used in electrical wiring, electronics, and plumbing due to its excellent conductivity properties.
Examples of very good conductors are: gold, silver, copper, aluminium, etc.
