Silver is considered to be relatively non-toxic to humans, though exposure to high levels of silver compounds can lead to argyria, a condition in which the skin turns blue-gray. Silver compounds can also have toxic effects on aquaticorganisms, and thus proper disposal and handling of silver-containing materials is important to minimize environmental impact.
Study Guide:
When studying silver, it's important to focus on its physical and chemical properties, its uses in various industries, and its environmental and health considerations. Here are some key points to consider:
What are the physical properties of silver, and how do they contribute to its uses?
What are the main uses of silver, and what properties make it suitable for these applications?
What chemical reactions can silver undergo, and how do these reactions contribute to its reactivity?
What are the environmental and health considerations associated with silver, and how can these be mitigated?
Energy - A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc 2 . B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion. C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy. D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields. E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.
