What is the noble gas notation of silicon (si) ? [ne] 2s22p2 [ar] 3s23p2 [ne] 3s23p2 [mg] 3p2

[Ne] 3s23p2

In noble gas notation the simplification in the electron distribution to the orbitals is represented where in of all of the lower filled orbitals up to the closest noble gas is enclosed by its symbols in brackets. The remaining orbitals are written in the usual way.The electronic configuration of Si is 1s22s22p63s23p2.The electronic configuration of Ne is 1s22s22p6. Thus the Noble gas notation of silicon (Si) can be written as [Ne] 3s23p2.

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   

Idon’t know what the answer is i wish i could
