"Quackism" is a recently discovered element with the symbol Q. It is located in group 7A of the periodic table, in the same group as bromine, chlorine and iodine.
How many valence electrons are associated with QO3- ?
(I call this e- math in the lecture videos.)
Apart from one atom of quackism, the ion also contains 3 oxygen atoms. Also, please take note of the very small negative sign on the formula of the compound.
