Final answer:
The combination that would form a neutral atom with no charge is which consists of 4 protons, 3 neutrons, and 4 electrons since a neutral atom must have the same number of protons and electrons. So the correct option is C.
Step-by-step explanation:
To determine which combination of protons, neutrons, and electrons would form a neutral atom with no charge, we must remember that protons are positively charged and electrons are negatively charged, while neutrons are uncharged. A neutral atom must have an equal number of protons and electrons because the negative charge of each electron cancels out the positive charge of each proton.
Looking at the provided options, we find:
- A. 3 protons, 3 neutrons, 4 electrons - This atom would have a net charge of -1, thus not neutral.
- B. 5 protons, 5 neutrons, 4 electrons - This atom would have a net charge of +1, thus not neutral.
- C. 4 protons, 3 neutrons, 4 electrons - This configuration would result in a neutral atom since the number of protons equals the number of electrons.
- D. 5 protons, 6 neutrons, 6 electrons - This atom would also have a net charge of -1, thus not neutral.
Therefore, the correct answer is option C: 4 protons, 3 neutrons, 4 electrons, which would form an atom with no charge.
