    Atomic Radius
Click For Summary
Transition elements do not follow the same atomic radius trends as main group elements due to their unique electron configurations and the presence of d-orbitals. While the atomic radius generally increases with atomic number (Z), the filling of inner d-orbitals complicates this trend. Experimental data should be referenced for accurate atomic radii, as theoretical predictions may not align with observed values. Users are encouraged to consult periodic tables and reliable resources for experimental mean atomic radii. Understanding these differences is crucial for accurate lab work and analysis in atomic physics.

im just doing a lab right now on atomic radius' and there's one question that asks, Would the transition elements follow the same trend that the maingroup elements follow for their atomic radius'?

i guessing yes, but I am not too confident with my answer.

anyone have any idea or know of resources to get information on this?

any help would be appreciated, thanks.

First guess,based on own logic:"Though it's one of their inner shells (either 3,4,5 or 6d) that get's filled,i would say that it should increase with Z".

Advice for you:Take a periodic table and search for mean atomic radii...This is experimental physics and own logic (in particular,mine) could be faulty...Especially when the equations that would account for the correct result (the one predicted by experiment) are impossible to solve...

thanks a lot daniel, i appreciate it

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
