Element 47 in our International Year of the Periodic Table series is silver. Silver compounds are key for film photography, and this element also pops up in your clothing: conductive gloves and some antibacterial socks contain it.
Another clothing-based use of silver is in the form of nanoparticles in clothes. Silver nanoparticles have antibacterial properties, so embedding them in socks, for example, can reduce odours resulting from foot bacteria. There are, however, some environmental concerns associated with this usage.
Up until relatively recently, silver’s most significant use was in film photography. Light-sensitive silver halide compounds made film photography possible. Digital photography has now largely taken its place for the majority of us.
