invariant
in mathematics and theoretical physics, property of a system which remains unchanged under some transformation
parity
flip in the sign of one spatial coordinate, in classical and quantum physics
charge
generalization of electric charge (EM) adding color charge (QCD), mass-energy (gravitation), etc.; sometimes considered same as its charge quantum number
symmetry
feature of a system that is preserved under some transformation
adiabatic invariant
property of a physical system that stays approximately constant when changes occur slowly, e.g. entropy
