The electron configuration for aluminum (al) is shown below: 1s22s22p63s23p1 which diagram shows the correct distribution of electrons in the electron shells of an aluminum atom?

No table found. the question asks for covalent bond based on electronegativies

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
