Best Answer: neutrons + protons = 23 ... Sodium Mass Number ... Na Mass Number ... Sodium (Na) Sodium has an atomic number of 11 and a mass of about 23g ... aprox ...
The mass number for iodine is 131, which is the sum of the protonsand neutrons. Iodine has 53 protons and 53 electrons, if neutral.To find how many neutrons iodine has subtrac â¦ t 53, the number ofprotons from the mass number of 131. This shows that iodine has 78neutrons.
