Answer 1

To determine which combination describes an ion with a positive charge, we need to look for a combination where the number of protons exceeds the number of electrons.

An ion with a positive charge is formed when an atom loses one or more electrons, resulting in more protons than electrons.

Let's analyze the options:

1. 7 protons, 7 neutrons, 8 electrons: Neutral, as protons = electrons.
2. 7 protons, 7 neutrons, 8 electrons: Neutral, as protons = electrons.
3. 8 protons, 9 neutrons, 8 electrons: Neutral, as protons = electrons.
4. 8 protons, 9 neutrons, 8 electrons: Neutral, as protons = electrons.
5. 10 protons, 9 neutrons, 10 electrons: Neutral, as protons = electrons.
6. 10 protons, 9 neutrons, 10 electrons: Neutral, as protons = electrons.
7. 9 protons, 9 neutrons, 8 electrons: Positive charge, as protons (9) > electrons (8).

The only combination that describes an ion with a positive charge is 9 protons, 9 neutrons, and 8 electrons.
