CHEMICALS PROPERTIES OF NICKEL

Nickel is a fairly abundant element, constitute about 0.008% of the earth's crust and 0.01% of igneous rocks. In some types of meteorites are no appreciable amount of nickel, and it is trought that there are large cuantities in the Earth's core.
Nickel is present in small mount in seawater, and most of the coal.
Metallic nickel is strong and hard (3.4 on Mosh scale), when finely divide it is black.
Resist corrosion and no alkaline swells into large pieces, but very thin wires can ignite.
In metallic form it is a strong reducing agent.
Most of the nickel compound are green or blue due to hydration or pther ligands binding to the metal.
 this is metallic 


NICKEL EFFECT ON HEALTH

Nickel is an element that occurs in the enviroment in very smalls levels.
Foods naturally contain small amounts of nickel. The chocolate and fats are known to contain high amounts. Nickel is taken and this will increase when people eat large amounts of vegetables from contaminated soils. It is known that plants accumulate nickel resulting nickel making plant be forthcoming. Smokers have a high degree of exposure to nickel through their lungs. Finally, the nickel can be found in detergents. Humans can be exposed to nickel by breathing air, drinking water, eating food or smoking cigarettes. The skin contact with contaminated soil or water nickel may also result in exposure to nickel. Nickel in small amounts is essential, but when taken in very large amounts it can be dangerous pair human health.
Taking hingh amount of nickel has a lot of consequences.


 this cupcakes can have nickel because are made with chocolate and chocolate have nickel.

ENVIROMENTAL EFFECT OF NICKEL


Nickel is released into the air by power plants and waste incinerators. This will be deposited on the ground or fall after reacting with raindrops. It usually takes a long period of time so that the nickel can be removed from the air. Nickel can also terminate on the surface of water when it is part of the wastewater. Most of all nickel compounds that are released into the environment by sediment or soil particles absorb becoming immobilized. In acid soils, nickel binds to become more mobile and often reaches groundwater.
High nickel concentrations in sandy soils can clearly damage plants and high nickel concentrations in surface water may decrease the range of algal growth. Microorganisms may also undergo a decrease in growth due to the presence of nickel. For animals nickel is an essential element in small quantities. But nickel is not only favorably as an essential element, it can also be dangerous when the maximum tolerable amount exceeds.

in this plant it can have nickel but not a lot.
