atomic weight - protons = neutrons,
Na-23 has an atomic weight of 23 amu, and 11 protons so 23-11=12 neutrons
Vanadium, Symbol V, is the element with atomic number 23.You can find the atomic number of an element from a periodic table as the one you'll find if you follow the link below. The number to the top of an element's symbol is the atomic number (that is , the number of protons in the nucleus.)http://www.electrical-res.com/EX/10-17-19/periodic_table_of_elements.jpg
An alkali metal that has 12 neutrons is sodium (Na), with an atomic number of 11 and an atomic mass of around 23 (which accounts for the protons and neutrons).
At No(F) + At No(Na) = 20.At No of Calcium = 20.
The symbol of sodium is Na and its atomic number is 11.
11...There are 11 electrons in Na1+ the only difference between Na1+ and Na is Na1+ has 1 more proton...there is no difference in electrons. Hope this helps :)
The atomic number of Na-23 is 11. This means that sodium-23 has 11 protons in its nucleus.
The atomic number of an element is equal to the number of protons in its nucleus. Since sodium (Na) has atomic number 11, the sodium isotope Na-23 with 12 neutrons must have 11 protons.

Sodium, symbol is Na
The standard atomic notation for the sodium-23 atom is: Atomic number (number of protons) = 11 Mass number (sum of protons and neutrons) = 23 Symbol = Na Putting it all together: ^23Na
Na is the chemical symbol and the Mass number is 23. The atomic number is 11.
