Study Notes
Basics of Atoms
- Atoms are fundamental particles of chemical elements.
- Each atom has a nucleus made up of protons and typically neutrons.
Structure of an Atom
- Electrons orbit the nucleus, held in place by electromagnetic forces.
- Protons are positively charged, while electrons are negatively charged.
Identification of Chemical Elements
- Chemical elements are identified by the number of protons in their atoms.
- Sodium has 11 protons, while copper has 29 protons.
Isotopes
- Atoms with the same number of protons but different numbers of neutrons are termed isotopes.
- Isotopes represent variations of the same element, affecting atomic mass but not chemical properties.
