Why do quarks have fractional charges if charge is quantized?

Does anybody know how quarks are formed? and why they always in fraction numbers like 1/3, 2/3. Since charge are always quantized. does this mean quarks are not quantized.?.

Hi astro2cosmos! Welcome to PF! :smile:

"Quantized" charge just means that it comes in multiples of a fixed amount … in this case, 1/3.

And quarks are probably fundamental, like electrons: not formed of anything. :smile:
 
If you look at the atomic orbitals, you will see charged clouds of partial charge too:
