Arrange the following elements in order of decreasing atomic radius:
Cs, Sb, S, Pb, Se
*(list from largest to smallest...or..."the correct ranking cannot be determined")
***I think the answer 'should be', from largest to smallest:
***Cs, Pb, Sb, Se, S***????
Am I correct in my thinking????
My periodic chart lists covalnt radius, as you have them listed as follows (all in Angstroms):
2.35; 1.47; 1.40;, 1.17; 1.02. Looks right to me.
this order came up being correct. Thank you
S, Se Sb, Pb, Cs
