What is Pb2? Important Pb2 knowledge

Definition of Pb2
Pb₂+ is a shorthand expression for the ion of lead with a valence state of +2, meaning it has lost two electrons from the outermost shell of the lead atom. This lead ion often appears in lead compounds, such as PbCl₂, Pb(NO₃)₂, PbSO₄, etc.
1.1 Names
1.1.1 Common name: Lead(II) ion
1.1.2 English name: Lead(II) ion
1.2. Atomic mass: 207.2
1.3. Atomic weight: 207.2 amu
1.4 Atomic structure: Pb₂+ has an outermost shell consisting of 14 electrons.

Properties: Pb2
Pb₂+ does not exist in a free state but only exists in compounds, so it does not have specific physical properties such as color, smell, or pH level. The chemical properties of Pb₂+ are expressed in the chemical reactions it participates in, such as reacting with acid to form lead(II) compounds or reacting with other metals to form lead(II) compounds.

Common chemical equations involving Pb2
Examples of some reactions that Pb₂+ participates in:
Pb₂+ + 2Cl- → PbCl₂
Pb₂+ + SO₄₂- → PbSO₄

Preparation of Pb2
In the laboratory, Pb₂+ can be prepared from dissolving lead in nitric acid to form lead(II) nitrate, then electrolyzing to separate Pb₂+ from the solution. On an industrial scale, Pb₂+ is typically produced by treating lead ore with acid or by electrolyzing lead compounds.
