Final answer:
The correct charge of the given particles: 6 protons, 7 neutrons, and 6 electrons is 6+.
Step-by-step explanation:
The correct charge of the given particles: 6 protons, 7 neutrons, and 6 electrons, can be determined by understanding the charges of these particles. Protons have a charge of 1+ while electrons have a charge of 1-. Neutrons, on the other hand, have no charge or a charge of 0. Therefore, the total charge of the given particles can be calculated by adding up the charges of each particle.
In this case, the total charge would be 6*1+ + 6*0 - 6*1- = 6+. So, the correct charge of these particles is 6+.
