When a neuron is polarized, usually by the influx of chloride ions into the neuron, it is incapable of creating an action potential (incapable of firing). Only when the neuron returns to a resting potential, via pumping ions back across the membrane, can it be depolarized (sodium ion influx) to generate an action potential.
There is electrical potential difference between out side of the cell and inside of the cell, in case of the polarized neuron. This electrical difference is lost in case of depolarization. That is what can be said roughly.
A polarized neuron has a more negative charge inside compared to the outside due to the presence of more negatively charged ions inside the neuron. This difference in charge is maintained by the activity of ion pumps and channels in the neuron's cell membrane.

The electrical condition of a plasma membrane of a resting neuron is polarized, meaning there is a voltage difference across the membrane with the inside being negatively charged compared to the outside. This resting membrane potential is typically around -70 millivolts.
When a neuron becomes excitable, it is able to generate and conduct electrical impulses known as action potentials. This excitability allows the neuron to communicate with other neurons through synaptic connections, facilitating the transmission of information within the nervous system.

A neuron that is polarized is also at rest potential. At this stage it is not conducting an impulse and has sodium ions on the outside and potassium ions on the inside.

An unstimulated neuron's membrane is polarized, with a negative charge inside the cell relative to the outside. This resting membrane potential is maintained by the unequal distribution of ions across the cell membrane, particularly sodium and potassium ions. The neuron is ready to generate an action potential when stimulated.

A neuron that is not sending a nervous impulse is typically referred to as a resting neuron. In its resting state, the neuron is polarized with a negative internal charge.
