The number of electrons,protons, neutron in a species are `18,16 `and `16` respectively. Assigns proper symbols

Explanation

To assign proper symbols to the species with the given number of electrons, protons, and neutrons, we can follow these steps:

### Step 1: Identify the Atomic Number
The atomic number (Z) is equal to the number of protons. In this case, the number of protons is given as 16.

**Calculation:**
\[ Z = \text{Number of Protons} = 16 \]
