Group 12 element a substance into the molten form of the metal, or through the process of electroplating which may be passivated by the use of chromate salts. Group 12 elements are also used in electrochemistry as they may act as an alternative to the standard hydrogen electrode in addition to being a secondary reference electrode. In the US, zinc is used predominantly for galvanizing (55%) and for brass, bronze and other alloys (37%). The relative reactivity of zinc and its ability to attract oxidation to itself makes it an efficient sacrificial anode in cathodic protection (CP). For example, cathodic protection of a
Tube Alloys national leader to approve a nuclear weapons programme on 30 August 1941. The Chiefs of Staff Committee supported the decision. A directorate of Tube Alloys was established as part of Appleton's Department of Scientific and Industrial Research, and Wallace Akers, the research director of Imperial Chemical Industries (ICI), was chosen as its head. Anderson and Akers came up with the name Tube Alloys. It was deliberately chosen to be meaningless, "with a specious air of probability about it". An advisory committee known as the Tube Alloys Consultative Council was created to oversee its work, chaired by Anderson, with its other
