Elements differ from one another according to the number of protons in the atoms' nuclei. Essentially, the number of protons indicate the element (not its reactivity).
11 is the atomic number of Sodium
Atomic number (in this case, 11,) is the number of protons in the element.
The 23 is telling you the atomic mass of the element (usually listed underneath the element symbol on the Periodic Table). The Atomic Mass of Sodium on the table is usually around 22.989.... so rounded to 23 for you in this question.
The atomic mass is the mass of protons plus neutrons(each about 1 atomic mass units).
Electron are so relatively light they do not significantly contribute to the mass of an element.

How many protons neutrons and electrons are in vanadium?
There are 23 electrons, 28 neutrons, and 23 protons in vanadium.
How many does 23 have?
atomic weight - protons = neutrons, Na-23 has an atomic weight of 23 amu, and 11 protons so 23-11=12 neutrons
How many protons neutrons and electrons are in fluorine- 23?
Number of neutrons = Mass number - atomic number = 23 - 9 = 14

Na-23 has 11 protons. How many neutrons does it have?
12
How many of each sub atomic particle does a c4 plus ion contain?
C4+ would contain 24 protons and 24 neutrons but only 23 electrons.
How many protons and neutrons are in sodium?
The atomic number of sodium is 11 so it has 11 protons. For Na-23 there are 12 neutrons (23 - 11 = 12)
