- Electronic Structure
- Electrons are found in shells surrounding the nucleus of an atom.
- The first shell holds 2 electrons, and every other one holds up to 8
- The shells fill up as they move across each period.
- The 1S subshell fills first follwed by 2S, 2P, 3S, 3P, 4S, 3D, 4P, 5S, 4D, 5P
- we show the electron configuration in boxes, representing each orbital with a box and the electrons with oppositely rotating arrows
- When filling the P and D orbitals, we put one electron in each box before we begin pairing up.
- Electrons are found in shells surrounding the nucleus of an atom.
- Copper and Chromium have unique electron configurations.
- copper is 1S2, 2S2, 2P6, 3S2, 3P6, 4S1, 3D10,
- The 3D orbital fills as it takes an electron from the 4S orbital to become more stable.
- Chromium is 1S2, 2S2, 2P6, 3S2, 3P6, 4S1, 3D5
- It fills the 3D sub-shell by taking an electron from the 4S sub-shell to again become more stable.
