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
1s2
Al+3 aluminum
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.
The electron configuration for aluminum atoms, which is 1s22s22p63s23p1.
The electron configuration of selenium for a 2- ion is [Kr]4s2.3d10.4p6.
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 the aluminum ion is identical to that of neon: 1s22s22p6
The electron configuration of thaliium III ion is [XE] 4f14 5d10.
The electron configuration of aluminum is [Ne]3s23p1.
Al3+
Al3+
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The most likely electron configuration for a sodium ion in its ground state is 1s22s22p63s1.
