The faster an atom moves around, the more heat it carries ... would lie if there were no motion due to heat; that is, if the metal's temperature were at absolute zero (-273°C).

The diagram shows a simple model of metallic structure. The metal ions are shown as tiny spheres, packed closely together in a regular pattern.

Chinese scientists have recently achieved the fabrication of single-atom-layer metals with a thickness of merely one-millionth of an A4 paper sheet, setting a new record for the thinnest metal ...

Atomic structure - AQA Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in shells. The number of subatomic particles in an atom can be calculated from the atom's ...
