In: Chemistry
pick one of the transition element and talk about the element's physical, chemical properties, preparation, discovery, and industrial application of that element
Solution.The transition elements are those elements having a
partially filled d subshell in any common oxidation state.
Ex:Nickel (Ni). It is generally exist in +2 oxidation state.(Common
oxidation state)
Discovery:Nickel was first isolated and classified as a chemical
element in 1751 by Axel Fredrik Cronstedt, who initially mistook
the ore for a copper mineral.
Physical
properties:1) Nickel is silver in colour.2) Nickel is
magnetic, hard,malleable, and ductile.3) MP is
1455oC,
BP is 2913oC
Chemical
properties:1)Corrosion: highly resistant to rusting and
corrosion2)Reactivity with Oxygen: Nickel metal does not react with
air under ambient conditions but in the finely dispersed state
nickel it ignites spontaneously in air.
3)Alloys: Stainless steel and copper-nickel alloy tubing.
4)Compounds: Used for electroplating and to make nickel
alloys
Applications.1)Nickel
is used in coins (because it remains shiny) and in
strong magnets (as an alloy with other metals).
2)Nickel compounds are used to color glass
green.3)Nickel is used in batteries, including
rechargeable nickel-cadmium batteries and nickel-metal hydride
batteries used in hybrid vehicles.
