No lead weights are just lead in the form of a wheight
No, lead is an element on the periodic table; it's symbol is Pb.
Lead is an element. The fact that it comes as shot, or fishing weights, or curtain weights, or some other form does not make it any thing other than an element. When it is mixed with other substances to create lead crystal, then it is a mixture.
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.
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.

No - lead weights are usually fairly pure lead and thus an element and not a compound.

Heterogeneous
Lead nitrate is a compound, as it is composed of lead, nitrogen, and oxygen atoms that are chemically bonded together in a specific ratio. It is not considered an element or a mixture because it is a pure substance with a fixed composition.
