Answer :
Answer:
Protons: 11
Neutrons: 12
Electrons: 11
Explanation:
A neutral sodium atom has the atomic number 11 and an average atomic mass of 22.989.
The atomic number is always equal to the number of protons.
The mass number is equal to the number of protons added to the number of neutrons.
So, to get the number of neutrons, just subtract the amount of protons from the mass number.
23 - 11 = 12 neutrons
For an atom to be neutrally charged, the number of electrons has to be equal with the number of protons, so this atom will have 11 electrons.
