Think I'm going to go to sleep, good luck guys.
Doesn't look like I'm getting any sleep...

For Gold, the answer is between 0 and 1.

Rg is just as bad guys, might sleep soon...

can't you give us a clue on how to work it out? I've been on this question for 2 hours :frown: I might be able to help on Rg
yeah, giving a range only helps us if we're guessing. We need a clue for the method.
I answered to 3DP, and I just found a random graph that had an energy value at that point, in eV, and converted that into Eh.
answered *what* to 3dp?

The question to 3DP.

Erm, I don't actually remember where I found it... I just googled strong nuclear force graph or something
