Barium is interesting with \(Z_m=56\), density \(3.51\,gcm^{-3}\) and molar mass \(137.327\,gmol^{-1}\)
\(v_{boom}=3.4354*\cfrac{3510}{56}=215.33\,ms^{-1}\)
\(T_{boom}=215.33^2*\cfrac{137.327*10^{-3}}{2*8.3144}=382.90\,K\) or \(109.75\,^oC\)
Does it glow green at \(T_{boom}=109.75\,^oC\)? Explosive! And poisonous!
