      The reason why it’s called antimatter is because the polarity of the nucleus and electrons are reversed. There are also antineutrons that have a neutral charge. It all still has mass, but will obliterate upon contact with regular matter

        There are also anti neutrons that have a neutral charge

        Expanding onto this, it raises the question: how is a neutron different to an anti-neutron?

        A neutron can be though of a particle composed of 2 down and 1 up quarks and lot of gluon’s that keep everything together. The gluon is its own antiparticle, so the antineutron has 2 anti-down quarks, 1 anti-up quarks and gluons. This way it becomes a different particle despite also being of neutral charge.

      yes, its the same as normal, its just the “Spin of the particles that are opposite”, if you get down deeper, the quarks are opposite.
