Dipole-induced dipole forces.
In contrast to C2H5OH, which is a very polar molecule, bromine is non-polar and has zero dipole moment. Charges are separated within polar molecules.
When a nonpolar Br2 molecule interacts with a polar C2H5OH molecule, one half of the bromine molecule acquires a charge and the other half acquires an opposing charge. A dipole is created when two adjacent bromine molecules have different charges. Bromine molecules must thus overcome the intermolecular forces—also known as dipole-induced dipole forces—that form in order to dissolve in ethanol.

A radioactive tracer, I believe. Someone check that lol.
Sulfur, selenium, and tellurium
its 640 because 150 goes into 900 6.4 times do you multiply 6.4 and 100 which is 640.
