The correct Answer is:
To determine the charge on the outer side of a neuron, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Neuron Structure**: - A neuron consists of a cell membrane that separates the inside of the neuron (intracellular) from the outside (extracellular). 2. **Ion Distribution**: - The distribution of ions is crucial for understanding the charge. Inside the neuron, there is a higher concentration of potassium ions (K+), while outside the neuron, there is a higher concentration of sodium ions (Na+). 3. **Charge Inside vs. Outside**: - The inside of the neuron is negatively charged due to the presence of negatively charged proteins and the higher concentration of potassium ions. - Conversely, the outside of the neuron has a higher concentration of sodium ions, which contributes to a positive charge. 4. **Conclusion**: - Given the higher concentration of sodium ions on the outer side, we conclude that the outer side of the neuron is positively charged. 5. **Final Answer**: - Therefore, the charge on the outer side of the neuron is **positively charged**.
