basically wtf is it? it has a mass, but not a charge..
usually masses without charges have an equal # of protons and electrons... but a neutron is a neutron.... ie what will happen if you bring an electron close a neutron? also.. protons and electron exhibit particle-wave duality, does the same apply to a neutron?

basically wtf is it [the neutron]?
Itīs a bound state of elementary particles called "quarks". Neutrons are part of every atomīs nucleus (except for nomal hydrogen). Without their presence, nuclei wouldnīt be stable.

The "usually masses without charges have an equal number of protons and electrons"-part is true for structures the size of an atom or greater. Particles like the proton and the electron are only about 1/100000 the size of a typical atomic diameter. At those scales, there are a lot of particles which are not as widely known as the "classics" proton, electron and neutron. They are -just like the proton and the neutron- bound states of above-mentioned quarks. The quarks do have electric charge and the charge of the bound state will depend on which quarks you combine (ie. the neutron-combination gives charge 0).
Besides those bound-quark states, thereīs also elementary particles being massive and neutral. The Z-Boson, for example, outweights the neutron by a factor 100 and is neutral, too.
Summary: Your statement above is true for size-scales greater or equal than those used in chemistry (-> atomic scale). Below, things become quite different.
also.. protons and electron exhibit particle-wave duality, does the same apply to a neutron?
Yes.
