Asap two different atoms have nine protons each and the same mass. however, one is neutral while the other one has a positive charge. describe what each atomic structure could be, listing the possible number and location of all subatomic particles

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
