""^28Si

Explanation:

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

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