Electrons that are involved in conducting electricity are predominantly found in which part of an atom?

The predominant location of electrons involved in conducting electricity is the valence shell of an atom. The valence shell is the outermost shell of an atom where the electrons are located, and these are the electrons that can participate in chemical bonding and electrical conductivity.

In metals, which are commonly used to conduct electricity, the valence electrons are often free to move throughout the material, allowing for the easy flow of electric current. This is in contrast to the protons, which are found in the nucleus of the atom and are positively charged. Neutrons, also located in the nucleus, are neutral and do not play a role in conductivity. Thus, it is the electrons in the valence shell that are crucial for conducting electricity, as they are the ones that can move freely in response to an electric field, enabling the flow of current in conductive materials.
