Answer;

Sodium (Na)

A single sodium atom has 11 protons, 11 electrons, and 12 neutrons.


Explanation;

For any neutral atom, the number of protons is the same as the number of electrons. If an atom loses or gains electrons, it is called an ion.

A sodium atom contains 11 protons, so its atomic number is 11. Mass number is the total of the protons and neutrons together, thus sodium has a mass number of 23.
