Given the mass of =25.6 g
The molar mass of =390.35g/mol
Converting mass of to moles:
Converting mol to mol S:
Converting mol S to atoms of S using Avogadro's number:
1 mol =
If there are no selections than i would say a thick atmosphere and an unusual large moon.<span />
As the period number increases on the periodic table, moving from top to bottom, the atomic radius of the elements increases as well.
