One alloy of this element is called Elektron and is used in aerospace engineering due to its low specific gravity.
One alloy of this element is called Elektron and is used in aerospace engineering due to its low specific gravity. Grignard reagants are composed of alkyl or aryl halides of this element, and ductile iron is most often created by using this element as a nodulizing element. This element's sulfate is combined with seven water molecules to create epsom salt and, with calcium, this element is the most common source of water hardness. This element can burn while encased in a block of dry ice or submerged in water, and the milk of this element is a suspension of its hydroxide. For 10 points, name this element that burns with a characteristic blinding white flare.
