Draw the Lewis structure of BH4- and use your Lewis structure to help fill in the missing numbers. Hint: you must put a number in each box. If the answer is zero, you must enter "0". The Lewis structure has: lone pairs = single bonds = double bonds = triple bonds = atoms with a positive formal charge = atoms with a negative formal charge = Is this structure stabilised by resonance? (Enter either yes or no below - no other words).
Decide whether the Lewis structure proposed for each molecule is reasonable or not. Note: If two or more atoms have the wrong number of valence electrons around them, just enter the chemical symbol for the atom as many times as necessary. For example, if two oxygen atoms have the wrong number of electrons around them, enter the symbol O twice.
