Study Notes
Valence Electrons in Nitrogen
- Nitrogen has five valence electrons, located in its outermost shell (2s² 2p³).
Electron Shells and Orbitals
- The second shell contains four orbitals: one s orbital and three p orbitals.
- This allows the second shell to hold a maximum of eight electrons.
Energy Levels of Electron Shells
- The energy level of a shell is determined by the principal quantum number (n), which corresponds to the shell's distance from the nucleus.
- Higher principal quantum numbers indicate higher energy levels and larger shells.
Size Comparison of Electron Shells
- The second shell is smaller than the third shell; as the principal quantum number increases, the size of the shells also increases.
Closed Shell Configuration for Carbon
- Atomic carbon has four valence electrons and needs four additional electrons to achieve a closed shell configuration, also known as an octet (eight electrons total).
