A metal with common valences of 2+ and 3+?

Question

I need to find a common household object that matches with these elements for my chemistry class. One of the item is a metal with common valences of 2+ and 3+. Another is an element with 29 electrons.

So pretty much, I need to know a metal with common valences of 2+ and 3+ and an element with 29 electrons.

Thanks
