Which of the following statements is correc O An atom of sodium has 11… Sodium’s atomic number is 11 and its mass number is 23. How many protons, electrons and neutrons does it have? The mass number defines the number of protons and neutrons in an atom. The atomic number shows the number of protons in an atom (nucleus). Because there is the same number of protons as electrons in an atom (uncharged atom), this number also indicates the number of electrons in an atom. Sodium is a chemical element with atomic number 11 which means there are 11 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. 11 Na Sodium 22.990. 12 Mg Magnesium 24.305. 13 Al Aluminium 26.982.
