Study Notes
Electronic Configuration
- Each shell can hold a certain number of electrons, which fill from lowest to highest energy.
- Within each shell, there are smaller regions called subshells.
- Electrons fill subshells according to the Aufbau principle.
Hydrogen Electronic Configuration
- The electronic configuration of hydrogen is 1s^1, meaning one electron is in the 1s subshell.
Carbon Electronic Configuration
- The electronic configuration of carbon is 1s^2 2s^2 2p^2, meaning there are two electrons in each of the 1s, 2s, and 2p subshells.
Shell Names
- Shells are named using the letters K, L, M, and N.
