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.
`""_(34)D`

Explanation

To solve the question, we need to determine the electronic configuration of the element with atomic number 34, identify its period, group, block, and class. Let's break this down step by step.

### Step 1: Write the Electronic Configuration
1. **Identify the atomic number**: The atomic number of the element is 34.
2. **Use the Aufbau principle**: According to the Aufbau principle, we fill the orbitals starting from the lowest energy level to the highest.

- Start filling from 1s:
- 1s² (2 electrons)
