Answer:
The relation between the shielding and effective nuclear charge is given as

where s denote shielding
z_{eff} denote effective nuclear charge
Z - atomic number
Explanation:
shielding is referred to as the repulsion of an outermost electron to the pull of electron from valence shell. Higher the electron in valence shell higher will be the shielding effects.
Effective nuclear charge is the amount of net positive charge that valence electron has.
The relation between the shielding and the effective nuclear charge is given as
wheres denote shielding
z_{eff} denote effective nuclear charge
Z - atomic number

We have the final answer as
<h3>227.27 mL</h3>
Hope this helps you
I don't know what you mean by just good, but electricity wise, no. In electricity they can't conduct very well and are just so called "heat carriers." They also have higher melting and/or boiling points. I found most of this on google so if you still are lost try looking up your question. Good luck! :)
