Nickel is a chemical element; ... Pure nickel is chemically reactive, ... An iron–nickel mixture is thought to compose Earth's outer and inner cores.
The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: 2 Na (s) + 2 H 2 O (l) →2 NaOH (aq) + H 2 (g) Metals in the middle of the reactivity series, such as iron , will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt ...
Nickel compounds are chemical compounds containing the element nickel which is a member of the group 10 of the periodic table. Most compounds in the group have an oxidation state of +2. Nickel is classified as a transition metal with nickel(II) having much chemical behaviour in common with iron(II) and cobalt(II).
A chemical element is a chemical substance whose atoms all have the same number of protons. The number of protons is called the atomic number of that element. For example, oxygen has an atomic number of 8, meaning each oxygen atom has 8 protons in its nucleus.
The surfaces of these metallic compounds provide a complex electron environment for catalyzing chemical reactions. [4] In steel metallurgy, nickel is alloyed with iron since 1888 (date of Schneider et Cie's patent [5] on nickel steel based on Jean Werth's research [6]) to produce maraging steel and some low-alloy steels.

The identity and relative number of the elements that make up a chemical compound, which can often be expressed with a chemical formula. chemical compound See compound. chemical decomposition The breakdown of a single particle or entity (such as a molecule or reactive intermediate) into two or more fragments, or a chemical reaction in which two ...
Organometallic compounds of the higher alkali metals are even more reactive than organosodium compounds and of limited utility. A notable reagent is Schlosser's base, a mixture of n-butyllithium and potassium tert-butoxide. This reagent reacts with propene to form the compound allylpotassium (KCH 2 CHCH 2).
