Look to your recipe for guidance on whether or not a nonreactive pot or pan is needed. Stainless steel cookware is typically considered nonreactive. Cast iron pots with an enamel finish are also non-reactive, unless there are any chips or cracks in the enamel. How do you know if aRead More →

The name derives from the Greek, anti + monos for “not alone” or “not one” because it was found in many compounds. The symbol Sb comes from stibium, which is derived from the Greek stibi for “mark” because it was used for blackening eyebrows and eyelashes. How did tin getRead More →

The very small atomic radius of osmium results in a small metal-metal separation. This small atomic separation along with osmium’s relatively high atomic number gives rise to osmium’s high density. Is osmium heavier than gold? Osmium is the most dense metal! Many people are familiar with lead (11.3 kg/L), butRead More →

Element 115 is one of a number of superheavy elements—elements with an atomic number greater than 104—that are so short-lived, they can’t be detected in nature. Scientists can, however, synthesize these elements in a laboratory by smashing atoms together. Can super heavy elements be stable? In nuclear physics, the islandRead More →
