Here's how to break down the number of atoms in 2NaCl:

* NaCl is a chemical formula for sodium chloride (table salt).

* The formula represents one molecule of sodium chloride.

* The subscripts indicate the number of each type of atom in the molecule:

* 1 sodium atom (Na)

* 1 chlorine atom (Cl)

* Therefore, 2NaCl represents two molecules of sodium chloride.

* To find the total number of atoms, multiply the atoms per molecule by the number of molecules:

* (1 Na + 1 Cl) * 2 = 6 atoms

So, 2NaCl has 6 atoms.
