An ion with a positive charge has more protons than electrons. In the options provided:
- 7 protons, 7 neutrons, 8 electrons - Neutral (1 more electron than protons)
- 8 protons, 9 neutrons, 8 electrons - Neutral (equal number of protons and electrons)
- 10 protons, 9 neutrons, 10 electrons - Neutral (equal number of protons and electrons)
- 9 protons, 9 neutrons, 8 electrons - Positive ion (1 more proton than electrons)
The correct response for a positive ion is 9 protons, 9 neutrons, 8 electrons as it has more protons than electrons.
