Out of the following identify (i) the *d' block element (ii) the of block element.
`Ca,Mn,U,Al`

Explanation

To identify the d-block and f-block elements from the given list of elements (Ca, Mn, U, Al), we will analyze the electronic configurations of each element step by step.

### Step 1: Identify the electronic configuration of each element.

1. **Calcium (Ca)**:
- Atomic number: 20
- Electronic configuration: \(1s^2 2s^2 2p^6 3s^2 3p^6 4s^2\)
