Explanation:

Step1: Identify the atomic number in the table

In the given table, each element has a number above its symbol. This number is the atomic number.
For example, for \(B\) (Boron) the atomic number is \(5\), for \(C\) (Carbon) it is \(6\), for \(N\) (Nitrogen) it is \(7\), for \(Al\) (Aluminum) it is \(13\), for \(Si\) (Silicon) it is \(14\), and for \(P\) (Phosphorus) it is \(15\).

Answer:

Si
