Indicate whether each statement is true or false. Drag the appropriate statements to their respective bins. the octet rule is based on the fact that filling in all s and p valence electrons in a shell gives eight electrons. compounds in which nitrogen is the central atom are frequent exceptions to the octet rule because they have too many electrons surrounding the nitrogen. boron compounds are frequent exceptions to the octet rule because they have too few electrons surrounding the boron. the si in sih4 does not follow the octet rule because hydrogen is in an unusual oxidation state.
