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 question, 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 fill the electrons according to the Aufbau principle.

1. **1s**: 2 electrons (1s²)
2. **2s**: 2 electrons (2s²)
3. **2p**: 6 electrons (2p⁶)
