Why does Lead (Pb) have a charge of 2+ or 4+

[From: ] [author: ] [Date: 11-04-22] [Hit: ]
.. so why does the charge of 2+ come in?Im sorry I really dont get in.-Lead has different oxidation states, or valencies.......
Can someone give me a detailed explanation, I really don't understand.

I thought Lead has four valence electrons... so why does the charge of 2+ come in?
I'm sorry I really don't get in.

Lead has different oxidation states, or valencies. The state in which lead reacts to form a compound depends what conditions it is reacted under:

For example:

If a Pb reaction occurs under high heat, the oxidation state it reacts as is 4+, and under less heat it will be 2+.
low heat: 2Pb + O2 = 2Pb(II)O
high heat: Pb + O2 = Pb(IV)O2

as codrakon says above.

although in several instances, you can find that it result +2 or +4 without heat taking any part in this. Chemically, for all multi-valence element like this, you can say that at any given oxidation number, it will reach a chemical stability.

Lead is of two types .One has valency as 2 while other has 4.
