    so ive been researching about the baryon number, charge and strangeness of quarks and i can only find the values of up, down and strange and its corresponsponding antiparticles. I cant seem to find the value for strange or or charm quark anywhere. is there a reason for this or is this just me being stupid? even my textbook doesnt contain it. help a fellow sttudent out and if you know the baryon number charge and strangeness values for the strange quark and the charm quark please do say

    Strange quark has a charge of -1/3 and a baryon number of +1/3.

    Not sure about charm (if this is A Level, it is not needed) but just for our curiosity: it has a charge of +2/3 but i can't find it's baryon number!
