The atomic number of Aluminium is 13. But the aluminium ion is lacking 3 electrons, so its electron configuration (10 e-) is as follows:
1s2
2s2 2p6
or in it abreviated form:
[Ne]
as it has the same number of electrons of Neon
The stable ion of aluminum is Al 3+, which means it has three fewer electrons. The aluminum atom has shed its outer shell of 3s2 3p1 and has an electron configuration equal to that of Neon, or 1s2 2s2 2p6.
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
The electron configuration for aluminum atoms, which is 1s22s22p63s23p1.
The electron configuration for the Co2 ion is Ar 3d7.
The electron configuration of a V3 ion is Ar 3d2.
The electron configuration of the Co2 ion is Ar 3d7.
The electron configuration of an Sc2 ion is Ar 3d1 4s0.
The electron configuration of 1s2 2s2 2p6 corresponds to a neutral atom of Neon (atomic number 10). A 3+ ion would have lost all its valence electrons, leaving behind a stable 1s2 2s2 2p6 configuration, giving it the electron configuration of a Neon ion.
The electron configuration of boron is 1s2 2s2 2p1. When boron becomes an ion, it typically loses its outer electron to achieve a stable electron configuration. Therefore, the electron configuration of a boron ion is typically 1s2 2s2.
The ion of aluminum typically has a charge of +3. This can be determined by looking at its position on the periodic table; aluminum is in group 13, and elements in this group usually lose three electrons to achieve a stable electron configuration. Therefore, the aluminum ion is represented as Al³⁺.
The electron configuration for the aluminum ion is identical to that of neon: 1s22s22p6
The electron configuration of an Fe ion is 1s2 2s2 2p6 3s2 3p6 3d6.
