उत्तर
| Lanthanoids | Actinoids |
| Their magnetic properties can be explained easily. | Their magnetic properties cannot be explained easily, as they are more complex. |
| Except promethium, they are non-radioactive | They are radioactive |
| Besides +3 oxidation state, they show +2 and +4 oxidation states only in few cases. | Besides +3 oxidation state, they show higher oxidation states of +4, +5, +6, +7 also. |
| Lanthanoid compounds are less basic | Actinoid compounds are more basic. |
