Bismuth contracts on cooling, rather than expanding. Its coefficient of thermal expansion is negative, meaning it contracts as it cools.
Depends on how much of the sample there is.
grey cast iron because during solidification the graphite flakes expands Bismuth and antimony are metallic elements that expand on solidification (~3-4%). These elements solidify in a monoclinic (not close-packed) structure which becomes more dense when it transforms from a solid to a liquid. A range of bismuth alloys are used for low temperature melt applications that have take advantage of the expansion to get close tolerance die castings. Gallium is a third metal element that expands during solidification (31 deg C).
No, bismuth nitrate is a compound composed of bismuth and nitrate ions, while bismuth oxynitrate is a compound that contains bismuth, oxygen, and nitrate ions. The presence of oxygen in bismuth oxynitrate makes it distinct from bismuth nitrate.
bismuth has six energy levels
Bismuth can be used in:- medicines- alloys- cosmetics- superconductors
Coke doesn't contain polonium or bismuth.
On heating. water molecules expand till they reach 100 cecius and break free from each other and turn into vapor. On cooling, when the temprature is 4 degree celcius, water starts to expand till it freeze.

Bismuth can be melted in a stainless steel pot atop a kitchen stove and very slowly cooled. The excess should then be poured into a stainless steel pot and depending on the length and evenness of the cooling process the crystals will be formed during the cooling period. Simple and easy. Requires 99.99% pure elemental metal or greater.

water contracts when cooling until about 4 deg. C. From that temp. further cooling causes the water to expand. as it freezes it continues to expand, that is why ice floats.

Bi is the symbol for bismuth.
Nope. Silicon(Si), Gallium(Ga), Antimony(Sb), Bismuth(Bi) and acetic acid(CH3COOH, vinegar) all expand on freezing as well. Moreover, silicon expands more than water on freezing (10% compared to waters 8%). The trick to this is that any substance with an open tetrahedral molecular structure will also expand upon freezing. (Perhaps phosphorus oxide(s))
