I'll solve this problem step by step, following the specified LaTeX formatting guidelines:

Step 2:
: Identify the Element

Aluminum is an element with a specific atomic number. To determine the number of protons, we need to look at its position on the periodic table.

Step 3:
: Determine the Atomic Number

Z_{Al} = 13
The atomic number of an element represents the number of protons in its nucleus. For aluminum, the atomic number is 13.

Step 4:
: Verify the Number of Protons

In a neutral atom, the number of protons is equal to the atomic number. Therefore, an aluminum atom has 13 protons in its nucleus.

Final Answer

Key Insight: The number of protons defines the element's identity. For aluminum, this means 13 protons are always present in its nucleus, regardless of the isotope.
