Al is aluminum and its number 13 well it has 13 electrons the reason why they put +3 is that u lose 3 electrons to make a full valence shell and if its negative 2 for example the number would be number 8 and add 2 more electrons which makes it a full valence shell
When aluminum (Al, #13) reacts, it loses its three valence electrons to achieve the same electron configuration as neon (Ne, #10.) That configuration is 1s22s22p6. So yes, Al+3 has the same configuration as neon.

The electron configuration for neutral Barium is [Xe] 6s2. Barium plus 2 means it has lost 2 electrons, so the electron configuration for Barium plus 2 would be [Xe].
The Fe2 plus electron configuration is 1s2 2s2 2p6 3s2 3p6 3d6.
Well, isn't that just a happy little question! The six ions that have the same electron configuration as Ne are He+, Li2+, Be3+, B4-, C5+, and N6-. They all have 10 electrons arranged in the same configuration as Neon, bringing a sense of harmony and balance to the world of chemistry. Just like painting a beautiful landscape, understanding these ions can bring a sense of peace and joy to your scientific endeavors.

When aluminum (Al, #13) reacts, it loses its three valence electrons to achieve the same electron configuration as neon (Ne, #10.) That configuration is 1s22s22p6. So yes, Al+3 has the same configuration as neon.
Al3+ is isoelectronic with neon with 10 electrons

AL has 3 more negative charges than positive ones
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.
Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.
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 neutral Barium is [Xe] 6s2. Barium plus 2 means it has lost 2 electrons, so the electron configuration for Barium plus 2 would be [Xe].
There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.
