The subatomic particles (protons, neutrons and electrons) can be determined using some basic information from .
The of an element is always equal to the number of protons. The of an element is equal to the protons added to the neutrons.
The element Sodium has an atomic number of 11 and an average of 22.98 which makes the mass number 23.
Therefore
An atomic number of 11 means this atom will have 11 protons.
A mass number of 23 means 23 - 11 this atom will have 12 neutrons.
Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons.
