Nickel is a metallic and silver-ish color, just like the US coin, the nickel (worth 5 cents).
Nickel(II) Oxide = NiO Nickel(III) Oxide= Ni2O3
Nickel(II) Oxide = NiO Nickel(III) Oxide= Ni2O3
The color of a US nickel is silverish. US nickels are actually made of 75% copper, but the silvery color of the remaining nickel 25% predominates.
Nickel (II) oxide is the correct chemical compound name.
By the color, obviously. NIckel plated flutes are slightly golden and well, silver plated, they have silver color.
Nickel II oxide exists as a solid at room temperature.
Nickel(II) Oxide = NiO Nickel(III) Oxide= Ni2O3
Nickel II oxide.
It is silver oxide that is Ag2O.
