Definitions:

Resting Potential

The difference in electric charge between the inside and outside of a neuron's cell membrane when the neuron is not actively transmitting a signal.

Depolarization

The process in which the difference in electrical charge across a cell membrane decreases, often leading to the initiation of an electrical signal.

Positively Charged

Having a net electrical charge due to the loss of electrons, often pertains to ions or particles.

Negatively Charged

Negatively charged refers to atoms or molecules that have more electrons than protons, resulting in an overall negative electrical charge.
