You already answered that...Mass, charge, momentum, spin, color, and whatever else I can’t remember because it’s too late.

But what do those terms mean? You mean subatomic particles have color, as in red, blue green? But they're so small, we can't see or photograph them.

You mean they spin like tops? And we can measure that? And their axis?

And if can only measure them at a single point in space, how do you measure for momentum?

I think the properties are measured by how the particles interact with other things...including momentum which determines how much energy is imparted during a collision. Can actually be seen (or the macro results) in a cloud chamber or by the sophisticated sensors at CERN or other facilities. Spin can be inferred as well.
