This isn't true even for fundamental particles. What about neutrinos?
Where's their charge?

In the left-helicity state, the neutrino has hypercharge g'/2, baryon
number -1/2, isospin g/2 and "chromaticity" coordinates (0,0) for the
SU(3) color force (i.e. the weights represented by the lambda3 and
lambda8 generators of the standard representation of SU(3))... where g'
= e/cos(T) and g = e/sin(T), where T is the weak mixing angle.

The neutrino is not known to exist in the right-helicity state (though
it is widely surmised, now, to do so). Its charge vector would be,
respectively, (0, -1/2, 0, 0, 0).

Baryon number is not known to be other than a global symmetry and,
therefore, not known to be associated with any force. Absent it, the
right-neutrino would be completely neutral and, therefore (almost)
completely invisible and undetectable. Only interaction with the Higgs
and gravity would reveal it. The mode of interaction between neutrinos
and the Higgs is an open issue (as is the existence of the Higgs).

Yes, I'm aware of all of that. I was simply asking about electric
charge, which I'm sure the OP was talking about also. And I gather
that he is probably not too familiar with the rest of the standard
model.

The standard model will only be
a model when someone can build it to scale and show
where and how all the various bits move and
fit together.

Already done. Most of this work was done between the '40s and the
'70s. By the end of the '70s most of it was already in place.

At present it is not a model.
It is a laughingstock.
There is no model at present.
There is smoke and mirrors but mostly

Don't citicise what you don't understand. It works pretty well. There
are, however, many unanswered questions, like where do all those
different particle masses come from?

A light photon of sufficient energy can
be passed in such a path that it
becomes a negatively-charged electron and
a positively-charged something else that isn't
permanent (positron).

Correct, but it doesn't depend on path, only on energy. A photon of
just the right energy can become an arbitrary particle-antiparticle
pair, but it requires an energy equivalent to twice the mass of the
particle to do this.

A free neutron disintegrates into.............what?

A proton, a beta particle (just a high energy electron) and an
antineutrino.

Many electrica;lly-neutral 'particles' break
up into charged 'bits'.
Charge makes up everything.

Neutrinos do not have electric charge. And they make up half of the
leptons.

What is the structure of your 'particles', then?

The truly fundamental particles are quarks and leptons. Hadrons are
made up of quarks. Leptons stand on their own. And if you don't know
what these words mean, look them up.

Of what are they made, Scotty?

Matter and energy.
