The electrical impulse causes chemicals called neurotransmitters to be released from the axon terminals of the pre-synaptic neuron which diffuseacross the synaptic cleft and fit into receptors on the post-synaptic neuron.
In an excitatory synapse, the presence of the neurotransmitters in the receptors of ligand-gated ion pores cause those pores to open and allow sodium ions into the post-synaptic neuron, which results in an electrotonic signal being conducted down the dendrite and soma to the axon hillock, which may initiate an action potential in the axon if enough signals are summed up at the axon hillock to reach a trigger value.
synapse is that junction through which impulse can be transmitted from one neuron to another.
It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.
The impulse has to cross over a synapse to another neuron or an effector.
An impulse travels in one direction across a synapse, from the presynaptic neuron to the postsynaptic neuron. This ensures that the signal transmission in the nervous system is unidirectional.

Chemical diffusion
It is most definitely a synapse.
No impulse is transmitted. Hence the all or nothing principal.

Nerve messages are called an impulse. Synapses are the space between two axons.
