You have to follow the Aufbau principle, which states that electrons populate the atomic orbitals situated at the lowest energy first.
The orbitals are:
1
22
333
4444
5555
666
77
Answer: The difference between these 3 isotopes is the number of neutrons.
The atomic mass of an atom is the number of protons plus neutrons. We know that the atomic number of magnesium is 12, so therefore there are 12 protons.
In Magnesium-24, there are 24-12 neutrons = 12 neutrons.
In Magneusium-25, there are 25-12 neutrons = 13 neutrons
In Magnesium-26, there are 26-12 neutrons = 14 neutrons
The correct answer is Nucleus.
I hope that helps! c:
