C. 11 protons, 11 electrons, 12 neutrons

Answer:

C. 11 protons, 11 electrons, 12 neutrons

Explanation:

Sodium is an alkali metal whose symbol is Na and atomic number 11. It is highly reactive metal as it is ready to donate a single electron which is present in its outer shell. In each sodium (Na) atom there is 11 protons and 12 neutrons as its atomic mass is 23 (11+12) and number of electrons will be 11 in a neutal sodium atom.
