**Ordering Elements by Ionization Energy**

The task presented is to order the following elements from lowest to highest ionization energy:

1. **Phosphorus, P**
2. **Silicon, Si**
3. **Sulfur, S**
4. **Aluminum, Al**

**Explanation of Ionization Energy:**

Ionization energy is the energy required to remove an electron from an atom. Generally, ionization energy increases across a period on the periodic table from left to right and decreases down a group. This is due to the increasing nuclear charge across a period, which holds the electrons more tightly, and additional electron shells down a group, which shield the outer electrons from the nuclear charge.

**Note:**
To determine the correct order, consider the position of the elements on the periodic table and trends in ionization energy.
