What is the noble gas configuration of aluminum?Group of answer choices[Ne] 3s23p1[Ne] 3s23p5[Ar] 4s23d7[Ar] 4s23p1[He] 2s22p63s23p1

The noble gas configuration of aluminum is [Ne] 3s2 3p1.

Here's the step by step process:

1. Identify the atomic number of aluminum. Aluminum (Al) has an atomic number of 13.

2. Write down the electron configuration. The electron configuration of aluminum is 1s2 2s2 2p6 3s2 3p1.

3. Identify the noble gas that comes before aluminum in the periodic table. The noble gas that comes before aluminum is Neon (Ne), which has an atomic number of 10.

4. Replace the electron configuration of the noble gas in the electron configuration of aluminum. The electron configuration of Neon is 1s2 2s2 2p6.

5. The remaining electron configuration after Neon is 3s2 3p1.

So, the noble gas configuration of aluminum is [Ne] 3s2 3p1.
