There is an error in the question - this is not an element as it would have an equal number of protons and electrons. 13 protons means it is Aluminum -12 electrons would mean it was Aluminum with one positive charge - which just does not happen. 17 neutrons would mean it is a heavy isotope of Aluminum Al30 - question needs to be rechecked and corrected
Al. The type of element is determined by the number of protons. All atoms with 13 protons are aluminum atoms. Aluminum has the symbol Al.
Mg, which is the element Magnesium. For future reference, the number of protons an element has is the same as its atomic number on the Periodic Table. Hope this helps you in the future.

Protons carry a positive charge and a symbol that represents that charge is a +/
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.
The center of an atom is called the nucleus.
- 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
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.
