Step 2:: Understand the Atomic Number
The atomic number of an element represents the number of protons in the nucleus of an atom. For aluminum, the atomic number is 13.
Step 3:: Determine the Number of Protons
Since the atomic number is 13, an aluminum atom has $$13$$ protons in its nucleus.
Step 4:: Determine the Number of Electrons
Therefore, an aluminum atom has $$13$$ electrons.
In a neutral atom, the number of electrons is equal to the number of protons.
Final Answer
- Number of protons in an aluminum atom: 13 - Number of electrons in a neutral aluminum atom: 13
