""^28Si28Si

Explanation:

If there are 14 protons, then, ZZ, the atomic number is 1414. Why? Because ZZ is by definition the number of positively charged, massive nuclear particles. And ZZ defines the identity of the atom; if Z=14Z=14, we gots "silicon........"silicon........

Because the element may contain more or less NEUTRONS than ZZ, where neutrons are massive, neutrally charged, nuclear particles, the isotope is ""^28Si28Si, about 92.2%92.2% abundant.
