An ion with a positive charge has more protons than electrons.

Let's analyze the provided combinations for positive ions:

  1. 9 protons, 9 neutrons, 8 electrons

    • Protons > Electrons (9 > 8), so this is a positively charged ion.

  2. 9 protons, 9 neutrons, 8 electrons (repeated)

    • Same as above, positively charged.

  3. 10 protons, 9 neutrons, 10 electrons

    • Protons = Electrons (10 = 10), so this is a neutral atom.

  4. 10 protons, 9 neutrons, 10 electrons

    • Same as above, it's neutral.

  5. 7 protons, 7 neutrons, 8 electrons

    • Protons < Electrons (7 < 8), so this is a negatively charged ion.

  6. 7 protons, 7 neutrons, 8 electrons (repeated)

    • Same as above, negatively charged.

  7. 8 protons, 9 neutrons, 8 electrons

    • Protons = Electrons (8 = 8), so this is a neutral atom.

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