✓
Answer
Lanthanides and actinides show similarities as follows :
- Both, lanthanides and actinides show+ 3 oxidation state.
- In both the series, the f-orbitals are filled gradually.
- Ionic radius of the elements in both the series decreases with increase in atomic number.
- Electronegativity in both the series is low for all the elements.
- They all are highly reactive.
- The nitrates, perchlorates and sulphates of all elements are soluble while their hydroxides, theorides and carbonates
are insoluble.
