number of protons, neutrons, and electrons in magnesium
Understand the Problem
The question is asking for basic information about the atomic structure of magnesium, specifically the number of protons, neutrons, and electrons it contains.
Answer
12 protons, 12 neutrons, and 12 electrons
The final answer is 12 protons, 12 neutrons, and 12 electrons
Answer for screen readers
The final answer is 12 protons, 12 neutrons, and 12 electrons
More Information
Magnesium's atomic number is 12, meaning it has 12 protons. In a neutral atom, the number of electrons equals the number of protons. Its most stable isotope, Mg-24, has a mass number of 24, resulting in 12 neutrons.
Tips
A common mistake is confusing the atomic mass with the number of neutrons. The atomic mass minus the atomic number gives the number of neutrons.
