The two elements that primarily help maintain a neuron's resting potential are **Potassium (K+)** and **Sodium (Na+)**.
At resting potential, there is a higher concentration of potassium ions inside the neuron and a higher concentration of sodium ions outside. The permeability of the neuron's membrane to these ions, largely influenced by ion channels, helps to establish the resting membrane potential. Anions (negatively charged ions) also play a role, but in the context of the two elements listed, potassium and sodium are the main focus.
