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 ions have a charge of 3+, as aluminum atoms lose three electrons to achieve the most stable electron configuration.
13 protons and 10 electrons in the atom
+3
Cl-1.
Al+3 aluminum
The electron configuration of selenium for a 2- ion is [Kr]4s2.3d10.4p6.
It loses 2 electrons and becomes a +2 ion.
It has 2 electrons in the first shell, and 8 in the second as it gains an electron to form an ion so the configuration is 2,8.
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?
Na+ ion.
Cl-
Cl-1.
Al+3 aluminum
It could be either Sn2+ ion (stannous ion) or Sn4+ ion (stannic ion)
The electron configuration of selenium for a 2- ion is [Kr]4s2.3d10.4p6.
It loses 2 electrons and becomes a +2 ion.
An anion is an ion that has a negative charge. It is formed when valence electrons are added to the outer energy level. It is giving the ion a stable electron configuration.
Sodium looses one electron to achieve noble gas electronic configuration.The formula of ion formed is Na+
Phosphorus ion (PĀ³ā») typically gains three electrons to achieve a stable electron configuration. As a result, it carries a charge of -3 and has a full outer electron shell.
