WitrynaThe third class contains metals such as chromium, iron, tin, and lead, which react only with strong acids. It also contains even less active metals such as copper, which only dissolves when treated with acids that can oxidize the metal. Metals in the fourth class are so unreactive they are essentially inert at room temperature. Witryna2 gru 2024 · The noble metals are a subset of the metals, but the membership in the group is not well-defined. The strictest definition of a noble metal is metal with a filled electron d-band.

Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air.
A lead atom has 82 electrons, arranged in an electron configuration of [Xe]4f 5d 6s 6p . The sum of lead's first and second ionization energies—the total energy required to remove the two 6p electrons—is close to that of tin, lead's upper neighbor in the carbon group. This is unusual; ionization energies generally fall going down a group, as an element's outer electrons become more distant fro… WitrynaThe largest number of elements are classed as liquids. nonmetals. metals. inert gases. metals The most active of the following metals is lead. copper. potassium. gold.
Witryna25 sie 2024 · For an inert complex, it is a large activation energy which prevents ligand substitution. Inert complexes are therefore kinetically stable compounds. As a classic example, the substitution reaction: (24.10.1) [ C o ( N H 3) 6] ( a q) 3 + + 6 H 3 O ( a q) + → [ C o ( H 2 O) 6] ( a q) 3 + + 6 N H 4 ( a q) + has an equilibrium constant of 10 64.
