Atoms of sg are very unstable, and it is therefore difficult to study this element's properties. based on the position of sg in the periodic table, what element should it most closely resemble in its chemical properties?

All " transuranium elements " ( i.e. an atomic number greater than 92 ) are unstable. Elements in the same family have similar properties. Based on this logic, one would expect seaborgium ( Sg ) to have similar properties to tungsten ( W ), which is directly above it in the same family.Elements of atomic mass 92 and above being most unstable called the transuranium group of elements is found to have many common properties and becomes difficult to judge on the basis of properties. Atomic number is the number of protons in the nucleus of the atom and it describes the chemical property of the elements.

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
