What is the atomic number of sodium chloride?

Answer 1

Sodium chloride, common salt, is a compound, and, therefore, HAS NO ATOMIC NUMBER!

We can speak the the atomic number of its constituent elements, i.e. sodium, #Z=11#, and chlorine, #Z=17#, which numbers represent the number of PROTONS, fundamental, massive positively charged nuclear particles, but this is all we can say with respect to atomic number.
We could speak of the formula mass of sodium chloride, #58.44# #g*mol^-1#, but that's another definition.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
