The electron configuration of aluminum (Al) is [Ne] 3s2 3p1
[Ne]3s23p1
The electron configuration "Ne 3s2 3p1" represents the electron arrangement for the element Sodium (Na). This configuration illustrates that Sodium has two electrons in the 3s orbital and one electron in the 3p orbital before bonding occurs.
Aluminum is [Ne]3s23p1 Sulfur is [Ne]3s23p4
[Ne]3s23p1
The electron configuration of aluminum is [Ne]3s23p1.
Aluminum (Al) follows the configuration of the noble gas before it, neon (Ne). Aluminum has 3 electrons in the 3rd level. Two of them are in the 3s subshell and the other is in the 3p subshell.[Ne]3s23p1
