Final answer:
The particle with 6 protons, 5 neutrons, and 7 electrons has a net charge of -1, as protons have a charge of 1+ each while electrons have a charge of 1- each and neutrons are neutral.
Step-by-step explanation:
To determine the correct charge of the given particles consisting of 6 protons, 5 neutrons, and 7 electrons, we must take into account the charge properties of each type of particle. Protons have a charge of 1+, while electrons have a charge of 1-. Neutrons are neutral with a charge of zero. The number of protons (positive charges) and the number of electrons (negative charges) need to be compared to determine the net charge.
For the given particles:
- Protons: 6 x 1+ = +6
- Neutrons: 5 x 0 = 0
- Electrons: 7 x 1- = -7
Adding the charges together:
+6 (for protons) - 7 (for electrons) = -1.
Therefore, the correct net charge of the particle with 6 protons, 5 neutrons, and 7 electrons is -1.
