Because a(n) ____ has its outer orbit filled or almost filled with valence electrons, they are tightly held in orbit and not easily given up for current flow.

Question

Quizplus · Accepted Answer

An insulator has its outer orbit filled or almost filled with valence electrons, making them tightly held in orbit and not easily given up for current flow. Conductors have outer orbits that are not filled, allowing electrons to flow freely, while semiconductors have their outer orbits partially filled and can be controlled to conduct or not conduct electricity. Transistors are electronic devices made from semiconductors that can amplify or switch electronic signals.
