章节摘录
In their work on atoms, scientists wondered whatkept the electrons spinning around the nucleus. Theydiscovered that the force of attraction between thepositively charged protons and negatively chargedelectrons keeps the electrons spinning. This madesense to the scientists because they had observed thatpositively charged things and negatively charged thingsare attracted to each other.But, what really interested scientists about electrons isthat they can move between atoms and as a result, createelectricity.Today, scientists and engineers use this knowledge tocome up with ways to get electrons to move betweenatoms to make new and amazing inventions that canmake our lives easier.
