Vedclass · Answer

(D) The nucleus of an atom contains only protons and neutrons.For $_{11}^{23}	ext{Na}$,the atomic number $Z = 11$ represents the number of protons.The mass number $A = 23$ represents the total number of protons and neutrons.The number of neutrons is calculated as $N = A - Z = 23 - 11 = 12$.Electrons are located outside the nucleus,not inside it.Therefore,the sodium nucleus contains $12$ neutrons.
