To determine which atom would be neutral, we need to consider the balance between the number of protons and electrons in the atom.

In a neutral atom, the number of protons (which have a positive charge) should equal the number of electrons (which have a negative charge). This balanced charge between protons and electrons creates an overall neutral charge for the atom.

Let's check the options:

A.) An oxygen atom with 16 electrons, 18 protons, and 16 neutrons:
The number of protons (18) is greater than the number of electrons (16), resulting in an overall positive charge. Therefore, this atom is not neutral.

B.) An oxygen atom with 9 electrons, 8 protons, and 8 neutrons:
The number of protons (8) is equal to the number of electrons (9), resulting in an overall balanced charge. Therefore, this atom is neutral.

C.) An oxygen atom with 8 electrons, 8 protons, and 9 neutrons:
The number of protons (8) is equal to the number of electrons (8), resulting in an overall balanced charge. Therefore, this atom is neutral.

D.) An oxygen atom with 4 electrons, 6 protons, and 4 neutrons:
The number of protons (6) is less than the number of electrons (4), resulting in an overall negative charge. Therefore, this atom is not neutral.

Based on the analysis above, the correct answer is B.) an oxygen atom with 9 electrons, 8 protons, and 8 neutrons.
