Question

how many protons, neutrons and electrons does a neutral atom of sodium have? one atom of sodium has blank protons, blank neutrons, and blank electrons. image of sodiums periodic table entry: sodium, 11, na, 22.990

Explanation:

Step1: Find proton count

The atomic number (11) equals proton count: $11$

Step2: Calculate neutron count

Round atomic mass to 23, subtract protons: $23 - 11 = 12$

Step3: Find electron count

Neutral atom has equal electrons/protons: $11$

Answer:

One atom of Sodium has 11 protons, 12 neutrons, and 11 electrons.
