Nickel is a moderate reducing agent.Silver-white metal, density of 8.9 grams / cm 3. Melting point ***5 , boiling point ***0 . Valence 2 and 3. Ionization energy of 7.**5 electron volts.
 
1.the introduction :Nickel is mainly used for electroplating, nickel-plated items is  beautiful, clean, not easily rust.
 
2..the element Uses: mainly used to make stainless steel and other corrosion resistant alloys, such as nickel steel, chrome-nickel steel and a variety of non-ferrous metal alloys, nickel-containing ingredients high copper-nickel alloy, it is unlikely that corrosion. Has made a hydrogenation catalyst and for ceramic products, specialty chemicals containers, electronic circuits, glass, green, as well as the preparation of nickel compounds, and so on.
 
3.the advantage:  Nickel-magnetic, which can be magnets attracting. The aluminum, cobalt and nickel alloy made of magnetic stronger. This alloy by the electromagnet to attract, not only  they will be smoking in the past, but it hung below its weight *0 times more than the things, it will not fall off. In this way, you can use it to create electromagnetic crane.
