The Neutron is not neutral. It is as negative as the proton is positive.

How in the world can one say that the neutron is not neutral? 

Let’s begin by talking about the proton and why it isn’t exactly positive. The reason we can state that protons are not really positive is that every proton is associated with an electron. If a proton joins the nucleus of an element, then we observe that an electron is also added. The number of protons in an element is equal to the number of electrons. Based on this, it is reasonable to propose that these electrons are actually each still associated with protons, which means the proton's positive quark structure is actually balanced by the negative charge of the respective associated electron. While the body of the proton acts in a positive way, because it is positive with two up and one down quarks, consideration of an associated electron lends validity to the hypothesis that the overall charge is actually neutral. 

Conversely, when one considers the structure of a neutron, with two down quarks and one up quark, the body should, and does, we can hypothesize, have a negative charge. But when we gauge the charge of a neutron it appears to be neutral. This proposed reality for the neutron is that it is essentially structured in exactly the same way as our neutral proton, with the difference being that the body is negative and that a positron, outside the body is in close orbit. The reason we perceive the proton as positive is due to the distant orbit of the associated electron, while with the positron, which orbits in close proximity to the neutron body, we see only neutral. The truth is that the neutron body is negative and it is orbited by a positron that is positive.
So, according to this hypothesis, the proton and neutron are truly opposite and equal, and they are positive and negative, respectively, and/or neutral, depending on whether one is considering the core body alone, or the core body in association with the respective positron or electron.

Taking this one logical step further, one may reasonably stipulate that a proton, at least in free state, is a hydrogen atom. A hydrogen atom is a proton orbited by a single electron, which in accord with the hypothesis advanced here is actually a proton. Perhaps hydrogen should have been named protonium.

Likewise, we venture onward, maintaining that there is always an opposite and equal, hypothesizing that the neutron, which does exist briefly in free state, actually also constitutes an element. This element is neutronium.
