Nickel is silver white in color when the metal is in its natural form. Nickel compounds express in blue, green and yellow.Know More
Nickel is a silver white crystalline metal and is the 22nd most abundant element on Earth. It is found in meteors or with other elements in ore groups. Nickel is found in laterites, which are oxide or silicate ores from in tropical areas. Nickel is also found in sulfides, which contain a small amount of nickel along with other metals such as copper and cobalt from cooler regions. The process of turning nickel oxides into pure nickel metal through purification developed in the late 19th century. In its natural state, nickel is magnetic and conducts electricity, but does not react quickly to oxygen.
Compounds and alloys of nickel are often blue or green in color, particularly when the compound is hydrated. Nickel oxide powder is used to make green glass. The same powder turns yellow when heated. Nickel oxide has occurred naturally in diamonds, where its presence produced a greenish yellow tint within the stone. Gemologists at the Gemological Institute of America, an organization that specializes in the classification and rating of gems, states that while nickel may be present within a diamond, a concentration high enough to color the stone is unusual.Learn more in Chemistry
Nickel is highly resistant to corrosion or rusting. However, when exposed to excessive humidity, nickel does corrode. When exposed to oxygen and moisture, nickel forms a thin layer of greenish colored nickel oxide. In an acidic environment, nickel begins to rust too.Full Answer >
Nickel is a solid metal element at room temperature and has a density of 8.912 grams per cubic centimeter. It is also a hard metal and has good corrosion resistance, which is why it is alloyed with other metals to improve toughness and increase their ability to resist corrosion.Full Answer >
In its natural form, salt does not have a pH balance. A pH balance is only used with solutions that are liquid based. The term pH refers to the hydrogen levels in a solution, which is what affects a solution's acidic/alkaline levels.Full Answer >
Phosphorus is a nonmetal. Nonmetals make poor conductors for electricity and heat and have high ionization energies and electronegativities. These elements are listed in the upper right side of the periodic table and include hydrogen, nitrogen, sulfur and selenium.Full Answer >
