Atomic number of chlorine is 17 and mass number is 35. Draw the structure of chlorine showing the composition of the nucleus as well as distribution of electrons in different shells. Also comment on its valency.

Explanation

To draw the structure of a chlorine atom and explain its composition, we will follow these steps:

### Step 1: Identify the Atomic Number and Mass Number
- The atomic number of chlorine (Cl) is 17, which indicates that it has 17 protons.
- The mass number of chlorine is 35, which is the sum of protons and neutrons in the nucleus.

### Step 2: Calculate the Number of Neutrons
- To find the number of neutrons, subtract the atomic number from the mass number:
