Two factors that determine whether a molecule is popular are the type of atoms in the molecule in the of the molecule

Polar bonds are formed when one atom in the bond has a much stronger pull towards electrons than the other atom. The difference in strength can be predicted by comparing electronegativity values. If one electronegativity value is higher, that atom will pull the electron closer and develop a slightly negative charge, while the other atom develops a slightly positive charge. Hope this helps!!

The duration of a photographic flash is related to an rc time constantly

Scissors and a seesaw both cut things that’s the only comparison
