* Electrons: Each electron carries a charge of -1.602 x 10^-19 Coulombs (C).

* Protons: Each proton carries a charge of +1.602 x 10^-19 Coulombs (C).

Calculation:

1. Total charge of electrons: 14 electrons * (-1.602 x 10^-19 C/electron) = -2.243 x 10^-18 C

2. Total charge of protons: 6 protons * (+1.602 x 10^-19 C/proton) = +9.612 x 10^-19 C

3. Total charge: -2.243 x 10^-18 C + 9.612 x 10^-19 C = -1.282 x 10^-18 C

Therefore, the total charge of 14 electrons and 6 protons is -1.282 x 10^-18 Coulombs.
