Answer 1

An ion with a positive charge has fewer electrons than protons. Therefore, to determine which combination represents a positively charged ion, we need to identify the options where the number of electrons is less than the number of protons.

Let's analyze the provided options:

1. 8 protons, 9 neutrons, 8 electrons: Charge = 8 (protons) - 8 (electrons) = 0 (neutral, not positive)
2. 8 protons, 9 neutrons, 8 electrons: Same as above, so neutral (not positive)
3. 10 protons, 9 neutrons, 10 electrons: Charge = 10 (protons) - 10 (electrons) = 0 (neutral, not positive)
4. 10 protons, 9 neutrons, 10 electrons: Same as above, so neutral (not positive)
5. 7 protons, 7 neutrons, 8 electrons: Charge = 7 (protons) - 8 (electrons) = -1 (negative, not positive)
6. 7 protons, 7 neutrons, 8 electrons: Same as above, so negative (not positive)
7. 9 protons, 9 neutrons, 8 electrons: Charge = 9 (protons) - 8 (electrons) = +1 (positive)

Based on the analysis, the combination that describes an ion with a positive charge is:

9 protons, 9 neutrons, 8 electrons.
