The third period element that forms a 3- ion is sulfur.
Aluminium, Al
[Kr]4d6 ion has 42 electrons. As it is a 3+ ion, the parent atom would have 45 electrons. This would make it Rhodium Rh.
Scandium, I believe it has something to do with that fact that it has the ability to have a double bond in ionic bonds. These diamagnetic metals between transition metals from the period 4 are copper and zinc.
Rhodium (Rh) forms a 3 plus ion that has the electron configuration Kr4d6. Rhodium has oxidation states of 2,3 and 4, so it can loan out 2, 3 or 4 electrons depending on the circumstances of a chemical reaction.
period 3
Chlorine, the halogen in period 3.
Aluminium, Al
Potassium. Sodium is in group1 (period2) the next heaviest element is potassium (period 3). Potassium forms salts with the K+ ion.

Arsenic will form a -3 Anion.
Rhodium (Rh) forms a 3 plus ion that has the electron configuration Kr4d6. Rhodium has oxidation states of 2,3 and 4, so it can loan out 2, 3 or 4 electrons depending on the circumstances of a chemical reaction.
a solid substance (s), a group 3 element, that forms a positive ion. it reacts with air, although this is not commonly known as it quickly forms a protective coating of aluminum oxide.
Phosphorus forms a -3 ion called phosphide.
Phosphorus usually forms compound negative ions as PO3-3 phosphite ion and PO4-3 phosphate ion in some cases P-3 phosphide ion also exists as in Ca3P2 as a positive ion phosphorus forms PH4+1 phosphonium ion.
Sulfide ion is S2- ion it is formed from the element sulfur gains two electrons. Sulfur belongs to group 16, period 3.
