An atom containing 7 protons, 8 neutrons, and 7 electrons: an atom containing 7 protons, 8 neutrons, and 7 electrons: cannot exist. is an ion. is charge-neutral. is an oxygen atom. none of the above

An atom containing 7 protons, 8 neutrons, and 7 electrons is charge-neutral.

Explanation:

An atom is composed of protons (positively charged), neutrons (no charge) and electrons (negatively charged). The excess or defect of electrons in relation to protons determines the charge of an atom.

An atom containing 7 protons, 8 neutrons, and 7 electrons:

cannot exist. FALSE.

is an ion. FALSE. Ions have positive or negative charges

is charge-neutral.  TRUE. Since the number of electrons is equal to the number of protons, the atom is neutral.

is an oxygen atom. FALSE. Oxygen atoms have 8 protons. 7 protons correspond to a nitrogen atom.

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry
