What is the relationship between the number of electrons and protons in a neutral atom?
The number of electrons is equal to the number of protons.
What is the main reason why materials with 1 - 3 valence electrons are considered conductors of electricity?
They tend to easily give away their 1 - 3 valence electrons to acquire stability following the octet rule.
What happens to the material when free electrons move in different directions?
The material acquires a static electric charge.
What is required to harness the power of static electricity?
Applying pressure to the material using a battery.
What determines whether a material is a conductor, insulator, or semiconductor?
The number of valence electrons in the atomic structure.
What is the term for electrons that are free to wander around the surface of a substance?
Free electrons.
What is the purpose of a battery in harnessing the power of static electricity?
To move free electrons in a single direction.
