Fornal Charge Exceptions?

Postby Jose Lupian 1C » Sun May 13, 2018 8:04 pm

Are there any elements in the periodic table that are exceptions to the formal charge equation or does the equation apply to all the elements?

I think I may have found one check this link out

"(The rare exception is a pure
covalent bond between two identical atoms such as in molecular chlorine, Cl-Cl.)
Because of this uneven sharing atoms have fractional, rather than integer, charges.
Calculations to determine
exact electron distribution and atomic charges require complex
computer programs and often many hours of computer time. "

"An exception that we need to take note of is for Helium (He). It is in group 18; however, it has only 2 valence electrons because its maximum number of electrons is 2. "
