The alkaline earth metals are found in group 2 of the periodic table. which alkaline earth metal has the highest ionic radius based on its location on the periodic table?

As you go down and to the left the ionic size of an element gets larger so radium (Ra) would be the largest in group 2.

I think group 2

Hope this helps

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
