  • Strontium: radii of atoms and ions - Periodic table

    One measure of size is the element-element distance within the element. It is not always easy to make sensible comparisons between the elements however as some bonds are quite short because of multiple bonding (for instance the O=O distance in O 2 is short because of the the double bond connecting the two atoms. The bond length in SrSr is: 430.3pm. ...
