Answer:

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.

The atom containing 7, 8, 7 protons, neutrons and electrons respectively has a neutral charge.

The atomic number corresponds to the number of proton which is 7 and the number of neutrons being 8.

An atom with a positive or negative charge would have an unequal number of proton and electron. Since the number of proton and electron is the same, then the atom is not an ion as it has the charge on the atom is (7 - 7 = 0).

An atom without a charge, that is; same number of proton and electron is the same. Hence, it is a neutral atom.
