# What element has the largest radius?

But as chemists, as physical scientists, we should seek out some $\text{noombers}$ to inform our argument. This site gives the atomic radius of francium as $1 \cdot \stackrel{\cdot}{A}$ where $1 \cdot \stackrel{\cdot}{A} \equiv 1 \times {10}^{-} 10 \cdot m$, which is a HUGE atomic radius.....and approaches actual bond lengths.........
