About Atomic Radius: empircal vs. calculated
« on: January 06, 2006, 01:34:40 PM »
I wonder which atomic radius data is more precise to the real cases, the empircal one or calculated one?

Depends who you ask. A theorist would say the calculated one and the experimentalist would say the empirical one.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Empirical means "verifiable or provable by means of observation or experiment".

I will side with the experimentalist.  :1eye:

So, what experiments did the scientists do?

Empirical ones.  Experimental data basically means that you measured it.  Theoretical predictions are useful when there are no ways of measuring radii experiementally, or if you want to predict the radius of an element that hasn't been discovered yet, or it has too short of a half-life.
