#""^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.
