Valence Electrons Quiz

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).
