To determine the largest neutral atom that can be built using the given particles, we need to consider the atomic numbers and electron configurations of each element.
Fluorine (F) has an atomic number of 9. Its electron configuration is 2-7.
Sodium (Na) has an atomic number of 11. Its electron configuration is 2-8-1.
Neon (Ne) has an atomic number of 10. Its electron configuration is 2-8.
Magnesium (Mg) has an atomic number of 12. Its electron configuration is 2-8-2.
To build a neutral atom, we need to balance the number of protons and electrons. The number of protons is determined by the atomic number, so we cannot change that. However, we can adjust the number of neutrons to create different isotopes of the same element.
Comparing the electron configurations, we can see that the largest neutral atom we can build is sodium (Na).
Use the simulation to answer the question.
