Ram Mohan looks at how bismuth — a remarkably harmless element among the toxic heavy metals in the periodic table — has sparked interest in areas varying from medicinal to industrial chemistry.

and all the elements in group 0 are unreactive non-metals. The zigzag, staircase, line in the diagram of the periodic table above separates the metals, on the left, from non-metals, on the right.

The Periodic Table is an amazing chemistry tool that is organized with elements in order of increasing atomic number. The properties of the element change as you move across the row, but are similar ...

Recent sampling shows that a high-alpine tributary of the Roaring Fork River, in addition to having high concentrations of ...

What's more, to the surprise of most chemists and going against the well-known trends of the periodic table, it turns out that francium is not the most reactive metal. On descending ... However, for ...

But this pretty, iridescent metal, found near the bottom ... However, its position in row six of the periodic table means bismuth also possesses some unusual heavy-atom properties.

Many of the pioneers of nuclear physics and chemistry feature in the list of heavy, radioactive ... where they seemed to sit in the periodic table, the elements after number 89, actinium, should ...
