30 POINTS!! Two different atoms have six protons each and the same mass. However, one has a negative charge while the other has a positive charge. Describe what each atomic structure could be, listing the possible number and location of all subatomic particles.

EXPLANATION:
We are told that both atoms contain 6 protons, so this must be an atom of carbon (atomic number = 6). These atoms have the same mass. Therefore they must contain the same number of neutrons in the nucleus, so they represent the same isotope. Without further information we assume that the isotope is carbon-12, which has 6 neutrons. It is assumed from the given information that one atom has a -1 net charge, while the other has a +1 net charge. Therefore the first atom has 7 electrons (excess of 1), while the second atom has 5 electrons (deficit of 1).

ANSWER: Number of protons in nucleus of each atom =
6
Number of neutrons in nucleus of each atom =
6
(assuming carbon-12)
Number of electrons surrounding nucleus of atom with -1 charge =
7
Number of electrons surrounding nucleus of atom with +1 charge =
5
