A bronze is an alloy of copper and other metals, most often tin, but also aluminium and silicon. Aluminium bronzes are alloys of copper and aluminium. The content of aluminium ranges mostly between 5% and 11%. Iron, nickel, manganese and silicon are sometimes added.
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Most iron alloys are steels, with carbon as a major alloying element.. Elinvar (nickel, chromium); Fernico (nickel, cobalt); Ferroalloys (Category:Ferroalloys) . Ferroboron ...
Iron oxide copper-gold deposits are also often associated with other valuable trace elements such as uranium, bismuth and rare-earth metals, although these accessories are typically subordinate to copper and gold in economic terms. Some examples include the Olympic Dam, South Australia, and Candelaria, Chile deposits.
Polymetallic nodules on the deep seabed in the CCZ Example of manganese nodule that can be found on the sea floor. Polymetallic nodules are found at depths of 4–6 km (2.5–3.7 mi) in all major oceans, but also in shallow waters like the Baltic Sea and in freshwater lakes.
Douglas D. Smith, a high school teacher, in a review of the 1st edition (without answers), says "The book is especially valuable to a general science teacher but has many items that relate to high school chemistry.
