Argon (symbol Ar) is the third element in group 18, the noble gases. In nature, sulfur can be found as the pure element and as sulfide and sulfate minerals. 4. covalent, because electrons are transferred, Ionic bond is defined as the bond formed when there is complete transfer of electrons from one atom to another atom. Answer: Three carbonate ions are required to bond with aluminum in a neutral ionic compound. Magnesium is also the metallic ion at the center of chlorophyll, and is thus a common additive to fertilizers. D. Two bodies with the same vibration frequency that are placed next to each other will exhibit sympathetic vibrations as one body causes the other to vibrate. It was needed to make the best quality of black gunpowder, and the bright yellow powder was hypothesized by alchemists to contain some of the properties of gold, which they sought to synthesize from it. All of the period 3 elements occur in nature and have at least one stable isotope.[1].
