What is the electron configuration of aluminum?
The electronic configuration of aluminum (Aluminium) is 1s2 2s2 2p6 3s2 3p1. This means that there are two electrons in the 1s orbital, two in the 2s orbital, six in the 2p orbital, two electron in 3s and one in the 3p orbital. The outermost electron is in the 3d orbital, which gives aluminum its chemical properties.

The electron configuration of aluminum in long form
Aluminum is a metal with the atomic number 13, meaning that it has 13 electrons in its outermost shell. The electronic configuration of aluminum in long form would be as follows: 1s2 2s2 2p6 3s2 3p1. This means that the aluminum atom has two electrons in its first shell, two electrons in its second shell, six electrons in its third shell, and one electron in its fourth shell.
The electron configuration of aluminum in short form
The electron configuration of aluminium in short form is [Ne] 3s2 3p1. This means that the aluminum atom has 13 electrons around the nucleus, with 2 in the first energy level, 8 in the second energy level, and 3 in the third energy level.
Draw an electron diagram for Aluminum
When writing electron configurations, we use the symbol [Xe] to represent a core of electrons surrounding the nucleus. The number of electrons in each element’s outermost orbital is its atomic number. So, for aluminum, we’d write [Ne] 3s2 3p1 as its electron configuration.
Aluminum is in period 3, so it has 3 orbitals: 1s, 2s, and 2p. Its outermost orbital is the 3s orbital, which contains 2 electrons. The next orbital out is the 3p orbital, which contains 1 electron.
Excited state and Ground state of Aluminum
The electronic configuration of aluminum in excited state is 1s2 2s2 2p6 3s1 3p2. The ground state of aluminum is 1s2 2s2 2p6 3s2 3p1.
Write down the unabbreviated name for Aluminium
The unabbreviated form of Electron configuration of Aluminium is [Ne] 3s2 3p1.
Properties and Occurrence of Aluminium
Aluminum is a chemical element with the symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal in the boron group. By mass, aluminum makes up about 8% of the Earth’s crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below. The top layer of the atmosphere contains 78% nitrogen and 21% oxygen; aluminum is found only in trace amounts (about 0.8 parts per million).
