List values in a typical neuron for 1) the resting membrane potential, 2) the na equilibrium potential (na), and 3) the k equilibrium potential (ek).

1. -30 to -90 mV

2. +60 to +80 mV

3. -84mV

Explanation:

In resting neurons, the resting potential ranges from 30 to 90 mV across the membrane. The inside membrane of a neuron is more negative as compared to the outside membrane. Thus, the inner resting potential of neuron varies between -30 to -90 mV.  

Equilibrium potential is defined as the potential across the membrane when the net flow is zero. This potential for sodium ion ranges between +60 to +80 mV

The equilibrium potential for K varies from -84mV.
