Screening effect

[oak inlet]

""""the 5f electrons are more effectively shielded from nuclear charge ."""""
In other words , the 5f electrons themselves to provide poor shielding from element to element in the actinoid series ,so the actinoid contraction is Greater from element to element then Lanthanide contraction..
Which has got good screening effect ?
4f or 5f and why ??

5f is more diffused

Short answer - you see data

And try and back track reasoning from there

[oak inlet]

5f : more diffused : wide spread : electron cloud more spread : poor shielding .
Sir could we say this ?
@scenic dune

[scenic dune]

not sure about wide spread

but rest is good
