only one valance electron does a conductor such as copper have.
good conductors have only one or two electrons in the outer shell while insulators have many more, around eight
Materials used for conductors generally contain 1 to 3 valence electrons, such as copper, silver, and gold. These valence electrons are free to move and contribute to the material's conductivity.
3
Because of their many valence electrons. The free-moving electrons transmit heat quickly.
Copper (Cu) has 2 valence electrons. It is located in the middle group of elements, called Transition Metals, and all transition metals have 2 valence electrons...hope that helped! =D
conductors
From one - e.g. Copper - to eight - e.g. Nickel.
Copper and aluminum are good conductors of electricity because they have many free electrons in their atomic structure. These free electrons can move easily through the material, allowing for the flow of electric current with minimal resistance.
Substances with many free electrons are good conductors of electricity. Metals like copper and aluminum are examples of materials with many free electrons and are commonly used in electrical wiring due to their ability to easily carry electric current.
Indium has 3 valence electrons.
Copper is element number 29. Thus, neutral copper has 29 protons and 29 electrons. The first 29 orbitals are filled as 1s2 2s2 2p6 3s2 3p6 4s1 3d10, thus copper has only one valence electron in its 4th shell.
