Question

atomic composition quick check
which atom would be neutral? (1 point)
an oxygen atom with 8 electrons, 8 protons, and 9 neutrons
an oxygen atom with 4 electrons, 6 protons, and 4 neutrons
an oxygen atom with 9 electrons, 8 protons, and 8 neutrons
an oxygen atom with 16 electrons, 18 protons, and 16 neutrons

Explanation:

Step1: Recall neutral - atom condition

A neutral atom has an equal number of electrons and protons.

Step2: Check each option

• Option 1: 8 electrons and 8 protons. Meets the neutral - atom condition.
• Option 2: 4 electrons and 6 protons. Not neutral.
• Option 3: 9 electrons and 8 protons. Not neutral.
• Option 4: 16 electrons and 18 protons. Not neutral.

Answer:

an oxygen atom with 8 electrons, 8 protons, and 9 neutrons
