> Copper, silver, and gold are in the same family of elements (group 11) and lead is in the carbon family.

By that, I'm guessing you mean in the periodic table. Been a while since I looked at that, should check it out again out of interest.

Yup, a lot of chemical properties are dictated by the number of outermost free ("valence") electrons, and atoms in columns in the periodic table all have the same number of valence electrons, hence similar chemical properties.

The University of Nottingham's School of Chemistry has some great, brief videos on various elements if you're ever interested: https://www.youtube.com/channel/UCtESv1e7ntJaLJYKIO1FoYw
