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 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.
Aluminum has trivalent cation. It is Al3+
Cl-1.
The ion symbol for magnesium is Mg2+ as it loses 2 electrons to achieve a stable electron configuration.
Aluminum typically forms the Al3+ ion which is stable due to achieving a full outer electron shell by losing 3 electrons.
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
A stable electron configuration for a chlorine ion can be achieved by gaining one electron. This would give the chlorine ion a full outer shell of electrons. The symbol for a stable chlorine ion with an extra electron would be Cl-.
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 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.
Na+ ion.
The electron configuration of a Copper(II)ion is [Ar]4s0 3d9.

1s2 2s2 2p6 is the electron configuration of the fluoride ion. It has a complete octet and is isoelectronic with neon. Before it becomes an ion, it is 1s2 2s2 2p5 Then it gains an electron and has a negative charge.
Aluminum has trivalent cation. It is Al3+
Fluorine's most stable ion configuration is F-, also known as the fluoride ion. Fluorine gains one electron to achieve a full outer energy level, making it isoelectronic with the noble gas neon and achieving a more stable electron configuration.
A. 35Cl1 is the symbol that represents a chlorine ion that has gained an extra electron to achieve a stable electron configuration.
