Study Notes
Electrons: Tiny Charged Particles
- Electrons are tiny particles within atoms, moving rapidly like planets around a sun.
- They possess a large amount of energy relative to their size.
- Electrons are found in all atoms, varying in number depending on the type of atom.
- An oxygen atom has 8 electrons; a copper atom contains 29.
- Atoms bond together by sharing electrons.
- This electron sharing creates entirely new substances.
- Metals like copper, aluminum, and iron are excellent electrical conductors due to easily transferable electrons.
- Electrical current, the flow of electrons between atoms, powers various devices.
- Electron transfer can be observed by rubbing a balloon on your head. The electrons in the hair and balloon are attracted to each other.
