Measurements of an artificial radioactive element called lawrencium could revive an arcane controversy over the element’s position in the periodic table — and the structure of the table itself. An ...

A ball and stick model can be used to show the structure of a simple molecule. This type of model has the advantage of showing how the atoms are connected and how they are arranged in space, including ...
