It is incorrect to state that an electron has exactly three times the charge of a naked quark. In the Standard Model of particle physics, the electron is an elementary particle with a fundamental charge of -1 elementary charge unit, denoted as e. On the other hand, quarks have fractional charges, with values of either +2/3 or -1/3 elementary charge units.
Quarks come in six different flavors: up (charge of +2/3), down (charge of -1/3), charm (charge of +2/3), strange (charge of -1/3), top (charge of +2/3), and bottom (charge of -1/3). The charges of the up, charm, and top quarks are +2/3, while the charges of the down, strange, and bottom quarks are -1/3.
It's important to note that the electron is not composed of quarks, and there is no direct relationship between the charge of an electron and the charge of a quark based on their numerical values. The charges of particles in the Standard Model are fundamental properties, and their values have been determined experimentally.
Therefore, the statement that an electron has exactly three times the charge of a naked quark is not accurate based on our current understanding of particle physics.
