Electrons are subatomic particles that have a negative charge and orbit around the nucleus of an atom. They play a crucial role in determining the chemical properties and behavior of elements.
Imagine electrons as tiny, fast-moving race cars on a racetrack (the electron cloud). Just like how different race cars can have different speeds and maneuverability, electrons can have different energy levels and positions within an atom.
Proton: A positively charged subatomic particle found in the nucleus of an atom.
Neutron: An uncharged subatomic particle found in the nucleus of an atom.
Atomic Number: The number of protons in the nucleus of an atom, which determines its identity as an element.
