it is a compund. It is a mixture of lead and nitric acid which are both elements
Pb is a compound.
Lead is an element, with the chemical symbol Pb and atomic number 82.
When silver nitrate is mixed with lead, a solid white precipitate of lead(II) nitrate is formed along with silver metal. This reaction is a displacement reaction where the more reactive silver displaces the less reactive lead from the compound.
Lead nitrate is a chemical compound with the formula Pb(NO3)2. In this compound, lead (Pb) is bonded to two nitrate (NO3-) ions. Therefore, there are three elements joined in lead nitrate: lead, nitrogen, and oxygen.
Lead and silver nitrate will react to produce silver and lead nitrate. Pb(s) + AgNO3(aq) --> Ag(s) + Pb(NO3)2(aq) We can know this by referring to an activity (also called reactivity) series for metals, which lists metals in a vertical list such that any metal will replace any metal below it on the list. Lead is above silver, therefore, the lead will replace the silver in the silver nitrate compound. For an activity series from Wikipedia, refer to the related link below.
No. It is an ionic compound.
This question is misguided. Firstly, Lead forms only the nitrate. Secondly, the phrase 'compound element' is meaningless. A compound is composed of elements. Lead nitrate is a compound composed of the elements lead, nitrogen and oxygen.

PbNO3 Lead (I) Nitrate Yes
It would be an alloy with some compounds (lead oxides) in a thin layer on its surface.
In its pure form it is a compound: sulphuric acid. But usually it is a mixture of sulphuric acid and lead sulphate.
Lead weights are typically made of a mixture of lead metal and other elements such as antimony or tin to increase hardness. So, lead weights are considered a mixture of elements.
Pencil lead is actually not lead (Pb) at all, but it is graphite. And graphite is simply carbons atoms. So, no, it is NOT a compound mixture.
The oxidation number of lead (Pb) in lead nitrate (Pb(NO3)2) is +2. In this compound, the nitrate ion (NO3-) carries a charge of -1, and there are two nitrate ions for every lead ion. The overall compound must be electrically neutral, making the oxidation number of lead in lead nitrate +2.

Pb(NO3)2 is an ionic compound. The lead (Pb) cation and nitrate (NO3) anion are held together by ionic bonds, formed by the transfer of electrons from lead to nitrate.
