Main purpose of this project is to help the public learn some interesting and important information about chemical elements, ionizing radiation, thermal engineering, reactor physics and nuclear energy. Its properties are thus intermediate between those of chlorine and iodine. [225] Zinc-deficient soil is cultivated in the cropland of about half of Turkey and India, a third of China, and most of Western Australia. [162] Zinc supplement is an effective treatment for acrodermatitis enteropathica, a genetic disorder affecting zinc absorption that was previously fatal to affected infants. [122], As a dense, inexpensive, easily worked material, zinc is used as a lead replacement. Excess zinc is toxic to plants, although zinc toxicity is far less widespread. Zinc pennies pose a risk of zinc toxicosis, which can be fatal. Major advantage of lead shield is in its compactness due to its higher density.

[22], Zinc metal is produced using extractive metallurgy. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidation in air. Electricity is produced because the Volta potential between the two metal plates makes electrons flow from the zinc to the copper and corrode the zinc. [169][170][182] It plays a key role in synaptic plasticity and so in learning. 6) Na + is formed from the reduction of Na(s). A 1994 trial showed that zinc doubled the rate of body mass increase in the treatment of anorexia nervosa.
