The no of electrons, protons and neutron in a species are equal to 10,11,12 respectively. Assign proper symbol to the species.

Explanation

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

### Step 1: Identify the number of protons
The number of protons in the species is given as 11. The atomic number of an element is equal to the number of protons. Therefore, the atomic number of this species is 11.

### Step 2: Determine the element
The element with an atomic number of 11 is Sodium (Na).
