Is lead a bohr or a Lewis model?
Lead can be represented using both the Bohr and Lewis models. In the Bohr model, the electron arrangement is shown in discrete energy levels, while the Lewis model represents the valence electrons as dots around the atomic symbol. Lead has an atomic number of 82, and in the Bohr model, it would typically have four layers of electrons surrounding the nucleus. In the Lewis model, lead would have four valence electrons represented as dots around the element symbol Pb.
What is a pure substance made of one atom and cannot be separated into simpler substances?

Why is model made to be simpler than the thing that it represents?
first of all it could be because models are usually in the microscopic level. and they dont have to be as specific as the real thing because they are only examples to help you understand something better
