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.

What is the isotope notation for sodium?
'Na' is the atomic notation of sodium. Hope this helps :)
How many protons neutrons and electrons are in fluorine- 23?
Number of neutrons = Mass number - atomic number = 23 - 9 = 14
How many protons neutrons and electrons in Sc with mass number 44?
21 protons, 21 electrons and 23 neutrons
How many protons and neutrons does a sodium with a mass number of twenty three have?
11 protons and 12 neutrons are there in Na-23.
If a particular isotope of sodium has a mass of 23 how many neutrons does it have?
An atom of Sodium weighs the same as 23 protons.
How many protons neutrons and electrons are in vanadium?
Vanadium has 23 protons, 23 electrons, and 28 neutrons.
How many protons electrons and neutrons does vanadium-52 have?
Vanadium-52 has 23 protons, 23 electrons, and 29 neutrons.
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
What is the isotope notation for sodium?
'Na' is the atomic notation of sodium. Hope this helps :)
How many protons neutrons and electrons are in fluorine- 23?
Number of neutrons = Mass number - atomic number = 23 - 9 = 14
What atom has an atomic number of 23 12 neutrons and how many electrons?
Vanadium has an atomic no. of 23 and mass number of 51. But it has 28 neutrons and 23 electrons
How many neutrons a phosphorus-23 atom has?
8
How many neutrons does Na plus have?
Sodium typically has 12 neutrons in its most common isotope, sodium-23. When sodium loses an electron to form the Na+ ion, it still has the same number of neutrons due to the neutral nature of neutrons.
How many electrons protons and neutrons respectively are in the iron III ion 56FE3 plus?
The iron III ion, 56Fe3+, has 26 protons, 30 neutrons, and 23 electrons. This is derived by considering the atomic number of iron (26) along with the charge of +3, which means it has lost 3 electrons.
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)
