Which combination of protons, neutrons, and electrons describes an ion with a positive charge? (1 point)

10 protons, 9 neutrons, 10 electrons

9 protons, 9 neutrons, 8 electrons

8 protons, 9 neutrons, 8 electrons

7 protons, 7 neutrons, 8 electrons

1 answer

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

Let's evaluate the options given:

  1. 10 protons, 9 neutrons, 10 electrons

    • Charge: 10 protons - 10 electrons = 0 (neutral)

  2. 9 protons, 9 neutrons, 8 electrons

    • Charge: 9 protons - 8 electrons = +1 (positive charge)

  3. 8 protons, 9 neutrons, 8 electrons

    • Charge: 8 protons - 8 electrons = 0 (neutral)

  4. 7 protons, 7 neutrons, 8 electrons

    • Charge: 7 protons - 8 electrons = -1 (negative charge)

The correct answer that describes an ion with a positive charge is:

9 protons, 9 neutrons, 8 electrons
