Each bond consists of 2 shared electrons, so there are 4 bonds \u00d7 2 electrons = 8 electrons used in bonding. This satisfies the octet rule for boron (though boron often is an exception, in this ion it obeys the octet).<\/p>\n\n\n\n Formal charge formula:<\/strong><\/p>\n\n\n\n Formal Charge = Valence Electrons \u2013 (Nonbonding Electrons + \u00bd Bonding Electrons)<\/strong><\/p>\n\n\n\n For Boron<\/strong>: For each Hydrogen<\/strong>: The overall formal charge of BH\u2084\u207b<\/strong> is \u20131<\/strong>. This result aligns with the fact that the ion is negatively charged and obeys the octet rule.<\/p>\n","protected":false},"excerpt":{"rendered":" What is the overall formal charge of BH4?
