Study Notes
Elements and Atoms
- The atomic number, which is the number of protons in an atom's nucleus, distinguishes one chemical element from another.
Atomic Structure
- Hydrogen-1 is the only atom that has no neutron.
Isotopes
- Atoms with the same number of protons but a different number of neutrons are called isotopes.
Atomic Observation
- Atoms are not visible with conventional microscopes because they are incredibly small and their size is measured in picometers.
Atomic Behavior
- It is not possible to accurately predict the behavior of atoms using classical physics because they exhibit wave-particle duality and other quantum mechanical properties.
