Sulfur is a chemical element with the symbol S and atomic number 16. It has 16 protons, 16 neutrons and 16 electrons.
Potassium and it has 19 electrons and protons and 20 neutrons. Potassium and it has 19 electrons and protons and 20 neutrons. Potassium and it has 19 electrons and protons and 20 neutrons.
It does not exist If it did exist it would be 30Al+
- The atomic symbol is only an abridged form of the name of a chemical element. - The chemical symbol of neon is Ne; the atomic number is 10. - The atomic number is equal to the number of protons and electrons. - Number of neutrons = Atomic mass of an isotope - Atomic number

Neon Ne is the chemical symbol for neon, a noble gass.
There are a variety of isotopes that have 30 neutrons. It isn't the number of neutrons that determines an element, but the number of protons. Electrons generally balance the number of protons.
So, all you have to look at is at the atomic number of the elements on the periodic table, which it is at the top of the symbol on the P.T, and that is the number of protons and electrons! Now, to find the number of neutrons, you have to find the number at the bottom of the element symbol called the atomic mass no. and you take away that by the top number.
Boron (symbol B, atom number 5) is build up with:5 protons, 5 electrons and 5 or 6 neutrons, depending on the mass number of the two possible isotopes: B-(10) has 5 neutrons and B-(11) has 6 of them respectively.
