Neurons are the conducting cells of nerve tissue. The neurons transmit the electrical charges and chemical signals via the synapses.
Dendrites
Contact between neurons, as you put it, is achieved through electrical impulses towards and from your brain.
Although there are many polar molecules in a resting neuron the overall charge is zero. Neurons don't actually send electrical pulses in the same way as computers or other electric circuits. The main neural transmitter that carries a charge across the synapse is acetylcholine not individual electrons.
A neutron carries no electrical charge
Yes, some objects have an electrical charge.
Neuton does not have any charge
Any ion.
A neutron carries a zero electrical charge and a mass of 1.674 x 10 -27 kg.

Electrical charges are conserved, meaning that any net electrical charge was present since the beginning of the Universe. I would expect the net electrical charge of the Universe to be zero; it is also possible to get electrical charges by separation of charges. That is, if you have a charge of 0, you can separate it into a charge of +1 and a charge of -1; the sum of the two charges is still zero.
