WebMolecules are defined as two or more atoms connected by covalent bonds. That might seem arbitrary (especially since covalent and ionic bonds are ends of a continuum rather … WebThe reacting species must collide in an orientation that allows contact between the atoms that will become bonded together in the product. The collision must occur with adequate energy to permit mutual penetration of the reacting species’ valence shells so that the electrons can rearrange and form new bonds (and new chemical species).
