Take Money Away from Your Bank Account and the Bank

Take money away from your bank account and the bank will show a negative credit.Take an electron away from an atom,however,and the atom shows up positive.Explain.

A) Electrons are already negative.Therefore,we know from basic math that subtracting a negative (number) from a neutral (atom) ,will make the result positive.
B) Neutral atoms contain identically charged but oppositely signed protons and electrons.Removing one of the negative electrons results in an excess of positively charged protons.
C) Removing an electron from an atom does not have the atom show up positive.It simply leaves the atom short one electron.
D) Atoms are constantly exchanging electrons.Having an atom "show up positive" is only an expression indicating that it has taken its turn in the game of electron exchange.
