A nickel is a US coin with a face value of 5 cents. It's an alloy rather than a compound, made of 25% nickel and 75% copper.
Nickel is a metal, an element with an atomic number of 28 and an atomic weight of 58.6934.
By itself or part of an alloy consisting of other metals. It can be also used as a compound - nickel (III) oxide - typically used in one specific type of rechargeable batteries (nickel-cadmium; NiCd)
Yes, nickel porphyrin compounds do exist. They are a class of organometallic compounds containing a central nickel atom coordinated to a porphyrin ligand. These compounds are commonly used as catalysts in a variety of chemical reactions.
The combination of oxygen and nickel can form various nickel oxide compounds, depending on the oxidation state of the nickel. These compounds can have different properties and uses, such as in catalysis or as pigments.
Nickel is an element on the periodic table with the symbol Ni and atomic number 28. It is a solid metal at room temperature and is commonly found in various compounds, but in its pure form, it is an element.
Yes, nickel can be found in the Caribbean region. Nickel deposits can be found in countries like Cuba, the Dominican Republic, and Guatemala in the Caribbean. These deposits are typically mined for the extraction of nickel ore.

Iron, nickel, and copper are not typically found in organic compounds, as they are considered inorganic elements. Oxygen, on the other hand, is commonly found in organic compounds, as it is essential for life and often forms bonds with carbon in organic molecules.
No, iron, oxygen, nickel, and copper are not commonly found in organic compounds. Organic compounds typically consist of carbon, hydrogen, oxygen, nitrogen, and other elements like sulfur and phosphorus. Iron, nickel, and copper are considered inorganic elements.
Yes, nickel porphyrin compounds do exist. They are a class of organometallic compounds containing a central nickel atom coordinated to a porphyrin ligand. These compounds are commonly used as catalysts in a variety of chemical reactions.
The combination of oxygen and nickel can form various nickel oxide compounds, depending on the oxidation state of the nickel. These compounds can have different properties and uses, such as in catalysis or as pigments.
lol ARE YOU DUMB it is of course iajf;ldjsf;LKFJ;ASLKDJFA;LDKFJ
In both compounds, nickel has a valence state of +3, meaning it has 3 valence electrons.
me dont know me either sorry!
Nickel is an element on the periodic table with the symbol Ni and atomic number 28. It is a solid metal at room temperature and is commonly found in various compounds, but in its pure form, it is an element.
Nickel is a naturally occurring element found in the Earth's crust. It is a silvery-white metal that is commonly used in various industrial applications like stainless steel production, alloys, and batteries. It is not synthetic, as it occurs naturally in the environment.
Platinum is a very rare element and expensive to refine. Very small amounts of platinum compounds are found during the processing of copper and nickel ores. The platinum compounds are separated from the other elements in the ore by a variety of electro-chemical processes.
Magnets can be made out of nickel, iron, cobalt, intermetallic compounds and chemical compounds.
