    Ionic Radius
AI Thread Summary
The discussion centers on the ordering of ionic radii for the ions Cl^-, Be^{2+}, Li^+, F^-, and H^-. The proposed order is Cl^-, H^-, F^-, Li^+, Be^{2+}, but there is uncertainty regarding the position of the hydride ion (H^-). The original poster expresses confusion due to differing opinions, particularly from their chemistry teaching assistant, who believes H^- should be last. The conversation highlights the complexity and potential controversy surrounding the ionic radius of H^-. Understanding periodic trends is essential for accurately determining ionic sizes.

Hi I have a question involving periodic trends. This time the trend is on ionic radius. I'm not sure I got this right so I was wondering if anyone here may please offer their advice. Thank you!

Question:
Order each of the following ions according to largest to smallest.
A. Cl^-
B. Be^{2+}
C. Li^+
D. F^-
E. H^-

Well have you read about the trend? It will make a lot more sense if you have read the information.
 
I have read the trend and I think the answer should be Cl-, H-, F-, Li+, Be2+.

However, I am not sure about this, because of the hydride. I heard that there is some controversy as what is the actual ionic radius. I just wanted to see if anyone here came up with the same order.

However, my chem TA disagreed and thinks the hydride should be last. What do you guys think?
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
