How many of each subatomic particle does a stable Sodium (Na) atom have?

(1 point)
• 23 protons, 12 neutrons, and 23 electrons
• 11 protons, 12 neutrons, and 11 electrons
• 34 protons, 11 neutrons, 11 electrons
• 11 protons, 11 neutrons, and 12 electrons

11 protons, 12 neutrons, and 11 electrons
Are you sure? Explain
My apologies for the mistake. A stable Sodium (Na) atom has 11 protons (as indicated by its atomic number), 12 neutrons (atomic mass minus the number of protons), and 11 electrons (equal to the number of protons for an overall neutral charge). Therefore, the correct answer is actually:
• 11 protons, 12 neutrons, and 11 electrons
