WebOxygen is electronegative because it only needs 2 electrons to complete it's valence shell. Instead of losing an electron (like sodium, in sodium chlorine), it simply attracts to those 2 electrons. The more a atom wants an electron, the more electronegative it is and visa versa. WebThus, boron commonly forms three bonds, BH \text {}_ {3} 3, with a total of six electrons in the outermost shell. This also results in some anomalous properties for boron compounds because they are kind of “short of electrons”.
