Study Notes
Atomic Structure
- The building block of matter that makes up everything we encounter daily is the atom.
Subatomic Particles
- The subatomic particle with a positive electrical charge, equal and opposite to that of the electron, is the proton.
Electron Orbitals
- An electron in an orbit or atomic orbital is described as being in the region in space with the greatest probability of finding the electron in an atom.
Pauli's Exclusion Principle
- The principle that states no more than two electrons in an atom can occupy an orbital and they must spin in opposite directions is known as Pauli's Exclusion Principle.
Lewis Electron Dot Structures
- The shorthand method consisting of a symbol of the element surrounded by dots, known as Lewis Electron Dot Structures (LEDS), was proposed by Gilbert Lewis.
Test your knowledge of atomic structure, including the arrangement of electrons in d and f orbitals, the Rutherford Model, and the properties of subatomic particles like protons.
