Which is the last element in the series of the actinods? Write the electronic configuration of this element. Comment on the possible oxidation state of this element.

Explanation

### Step-by-Step Solution:

1. **Identify the Last Element in the Actinide Series**:
- The actinide series consists of 15 elements, from actinium (Ac, atomic number 89) to lawrencium (Lr, atomic number 103).
- The last element in this series is **lawrencium (Lr)**, with an atomic number of **103**.

2. **Determine the Electronic Configuration of Lawrencium**:
- The electronic configuration of lawrencium can be derived based on the Aufbau principle and the order of filling of orbitals.
