Sodium has an atomic number of 11 and a mass number of 23. Which of the following are the correct number of protons, neutrons, and electrons respectively, in a neutral sodium atom? a 11,11,12 b 11,12,12 C 11,11,11 d 11,12,11

## Step 1: Identify the number of protons### The atomic number of sodium is 11, which indicates that sodium has 11 protons.## Step 2: Identify the number of electrons### In a neutral atom, the number of electrons equals the number of protons. Therefore, sodium has 11 electrons.## Step 3: Identify the number of neutrons### The mass number is the sum of protons and neutrons. Given that sodium's mass number is 23 and it has 11 protons, the number of neutrons is .
