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.
