Answer:
Thus, helium has the largest first ionization energy, while francium has one of the lowest.
__MgF2 + __Li2CO3 + __ 2LiF
Formal charge can be calculated from the following formula
Formal charge = valency of central atom - (number of lone pair of electrons + number of covalent bonds)
a) for methylene:
Formal charge = 4 -( 2+ 2) = 0
b) For methyl free radical
Formal charge = 4- (3 +1) = 0
