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.
`""_(74)E`

Explanation

To solve the question regarding the element with atomic number 74, we will follow these steps:

### Step 1: Determine the Electronic Configuration
1. The atomic number of the element E is 74.
2. We start with the nearest noble gas preceding it, which is Xenon (Xe) with an atomic number of 54.
3. After Xenon, we need to fill in the remaining electrons:
- 74 - 54 = 20 electrons left to place.
4. The filling order of orbitals follows the Aufbau principle:
...
