Physical change I’m pretty sure
Pb2+(aq) + CO3 2-(aq) ==> PbCO3(s)
Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction. ... Materials that conduct electrical current easily are called conductors and have a low resistivity. Those that do not conduct electricity easily are called insulators and these materials have a high resistivity.
Most elements tend to have the same number of electrons and protons. This gives the element a neutral charge, aka no charge at all.
Here is an example:- Flourine
7 electrons and 7 protons
