The total number of electrons present in `4^"th"` shell of Xenon (`._54Xe`) are:

Explanation

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

### Step 1: Identify the atomic number of Xenon
Xenon has an atomic number of 54. This means it has 54 electrons.

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