See the technical phrasing
The sodium-potassium pump maintains resting membrane potential by actively transporting sodium ions out of and potassium ions into the neuron, thereby preventing spontaneous neuronal firing.
The sodium-potassium pump moves three sodium ions out of the neuron and two potassium ions into it for every molecule of ATP it uses. This creates a net loss of positive charge inside the cell, making the inside more negative than the outside. This negative voltage keeps the neuron calm and prevents it from firing randomly. When the pump works poorly, the inside of the neuron becomes less negative, making it easier for the neuron to fire without a signal. When the pump works better, the neuron becomes more negative and harder to trigger accidentally.
