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 of determining the electronic configuration, period, group, block, and class of the element with atomic number 54 (which is Xenon, Xe), we can follow these steps:

### Step 1: Determine the Electronic Configuration
The electronic configuration of an element describes the distribution of electrons in its atomic orbitals. For Xenon (atomic number 54), the electronic configuration can be determined as follows:

1. Fill the orbitals in the order of increasing energy levels according to the Aufbau principle.
2. The order of filling is as follows:
- 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p.
