The total number of electrons present in `4^"th"` shell of Bromine (`._35Br`) are:

Explanation

To determine the total number of electrons present in the 4th shell of Bromine (Br), we will follow these steps:

### Step 1: Identify the atomic number of Bromine
Bromine has an atomic number of 35. This means it has 35 electrons when it is in its neutral state.

### Step 2: Write the electron configuration of Bromine
The electron configuration of Bromine can be written as:
\[ \text{Br: } 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^{10} 4p^5 \]
