How Neptunium Differs From Other Actinides
Neptunium is the first actinide with electrons in the 6d subshell. Earlier actinides like thorium and protactinium have fewer 5f electrons. This shift changes its reactivity and bonding.
Compared to uranium, neptunium has one less 5f electron but one 6d electron. Later actinides fill the 5f orbitals more fully and less often use the 6d orbital.
Similarities In Electron Filling Patterns
All actinides fill the 5f orbitals as they increase in atomic number. The 7s electrons remain constant in the early actinides. This pattern affects their magnetic and chemical behavior.
Neptunium shares this gradual 5f filling pattern with other actinides. This helps explain trends in their physical and chemical properties across the series.
