1
Electron Configurations
“An element’s permanent address.”
2
Wave Function (Un-neat Orbits)
Heisenburg Uncertainty Principle It is impossible to determine the exact location and speed of an electron. What is an orbital? A 3-D region around the around the nucleus that indicates the probable location of an electron.
3
The 4 Element Orbitals s orbital p orbital d orbital f orbital The orbital where an electron may be found depends on the energy level which directly aligns to where an element is positioned in the periodic table.
5
Electron Configurations The arrangement of electrons in an atom.
6
Write the Electron Configuration:
Carbon Potassium Zinc Rubidium Iodine
7
Write the Shorthand Configuration:
Yttrium Sulfur Arsenic
8
Orbital Diagrams Orbital diagrams tell you the energy level, spin, and probable location of an electron in an atom. One orbital holds 2 electrons: s orbital = 2 electrons = ________ orbitals p orbitals = 6 electrons = ________ orbitals d orbitals = 10 electrons = ________ orbitals f orbitals = 14 electrons = ________ orbitals
