Simplifique esta solución Beyond the Answer
In a neutral atom of magnesium, the number of electrons equals the number of protons, which is 12 for magnesium, regardless of the isotope. While isotopes of an element vary in the number of neutrons, the number of protons—and thus electrons in a neutral atom—remains the same.
So, the correct answer is (B) 12 electrons! It’s as simple as counting to twelve!
