The correct response is: **the number of protons**.
The number of protons in an atom's nucleus determines its atomic number, which defines the element and its identity.

The correct response is: **It will react with other nearby atoms to give, receive or share electrons until it has a full outer shell.**
According to the octet rule, atoms tend to react in ways that allow them to achieve a full outer shell of electrons, typically consisting of eight electrons.

To answer the question regarding the largest neutral atom you can build from the choices given, the correct response is: **neon (Ne)**.
Neon is a noble gas and is represented by the atomic number 10, meaning it has 10 protons (and 10 electrons for neutrality). This is larger than sodium (11 protons), fluorine (9 protons), and magnesium (12 protons) in terms of atomic number, but in the context of the choices given, it seems there may be some confusion about the "largest" based on atomic size or atomic number. However, if we consider the atomic numbers, magnesium is the largest (12 protons) but is not the correct option here as the question seems to ask for neutral atoms specifically from the context.
Therefore, **magnesium (Mg)** is the largest neutral atom listed as it has the highest atomic number (12) among the given options.
Given that the question is likely meant to ask about elemental options provided, **magnesium (Mg)** is the ideal answer based on atomic number constraints.
