because if you were to write PB then it would be a compound not a single element while Pb is lead.
The dissolution reaction for lead(II) nitrate, Pb(NO₃)₂, in water can be represented as follows: [ \text{Pb(NO}_3\text{)}_2 (s) \rightarrow \text{Pb}^{2+} (aq) + 2 \text{NO}_3^{-} (aq) ] In this reaction, solid lead(II) nitrate dissociates into lead ions (Pb²⁺) and two nitrate ions (NO₃⁻) when it dissolves in water.

lead Latin name plumbum shortened to Pb
The chemical name is lead. The symbol for the element lead is Pb, for plumbum, which comes from Latin for lead.

Pb is a compound.
Pb(IV) compounds are powerful oxidizing agents because of the high oxidation state of lead in these compounds (+4). This high oxidation state results in a high affinity for gaining electrons, making Pb(IV) compounds effective at accepting electrons from other species, thereby oxidizing them. Additionally, the presence of multiple oxygen atoms in Pb(IV) compounds further enhances their oxidizing potential.
