Answer:

An ion contains an #"EXCESS or DEFICIENCY"# of electrons.......so you tell us!

Explanation:

A neutral atom can lose an electron to become a cation:

#MrarrM^(+) + e^-#

Or gain an electron to become an anion:

#M+e^(-)rarrM^-#

So which is the neutral species?

Note that all chemical reactions conserve mass and charge. Are mass and charge conserved here? How? Why can't a given atom lose the other, POSITIVELY charged, particle.
