hey guys!
I was just wondering if anyone could help me out a bit on this.
I have the following radii (in angstroms...not that it really matters)
Ca: 1.74 Ca 2+: .99
Zn: 1.31 Zn 2+: .74
Does anyone have any idea why the difference between the atomic radii of the two elements is greater than the ionic radii of the two ions? (atomic difference is .43 and the ionic diff is .25)
I've asked a bunch of people (friends in my class, parents, parents of friends etc.) and no one has any ideas
Can you help?
thanks!
