- The general valence shell electronic configuration of actinoids is $5{f^{1 - 14}}6{d^{0 - 1}}7{s^2}$.
- As they contains seven shell they are placed in seventh period and third group of periodic table.
- They interrupt fourth transition series in seventh period.
- They are placed at the bottom of periodic table only for convenience actually they are placed in seventh period.
