Write the electronic configuration of the elements given below and predict their period, group, block and also name the class, i.e., representative, transition etc. to which they belong.
`""_(54)A`

Explanation

To solve the problem, we will follow these steps:

### Step 1: Determine the Electronic Configuration
The atomic number given is 54, which corresponds to the element Xenon (Xe). We will write the electronic configuration for Xenon.

1. The order of filling the orbitals follows the Aufbau principle, which states that electrons occupy the lowest energy orbitals first.
2. The electronic configuration can be written as follows:
- 1s²
